It may seem like an impossible task to keep up with all the Twitter apps that have come to market as of late. Even though you have plenty of directories to help with the process, we noticed that it’s still difficult to ascertain which apps support multiple accounts.

As more and more people are using Twitter for personal and professional reasons, the demand for a Twitter client to match those multifaceted needs is rising. Here are several options to help you tweet now or later from different accounts on your desktop, via the Web, and while on the run. We’ve also included a few browser add-ons and business-specific clients to help you find the right application to suit your Twittering needs.

Desktop

Nambu: A great single or mutli-column app for multiple Twitter, Identi.ca, and Laconi.ca account management. Nambu also includes Twitter trends, saved searches, filters, link aggregation, and groups. Plus, if you have a Nambu account you can use tr.im to shorten URLs, and pic.im for better Twitter photo tools than Twitpic.

Seesmic Desktop: A viable threat to TweetDeck, Seesmic Desktop has no limitations on the number of accounts you can manage. Plus, since it fully integrates with Facebook, and also allows for unlimited columns, it’s a fantastic way to engage with Twitter from your desktop.

Twhirl: Even though Seesmic Desktop is the replacement desktop application for Twhirl, it still continues to dominate the TwitStat Twitter client leader board (currently in the number 5 slot). Users love having multiple account support and a single column view of tweets. Also of note is cross-posting to Ping.fm, and the ability to record and follow Seesmic videos.

Tweetie for Mac: This single column gem launched with a bang, thanks the popularity of their mobile app. We’re mad about Tweetie for Mac’s sleek design, which does an amazing job at multiple account management while respecting our screen real-estate. Power users will enjoy the keyboard shortcuts, conversations, and threaded direct messages.

Twibble Desktop: Twibble allows users to manage up to 3 different Twitter accounts, and includes keyboard shortcuts, location awareness, and viewing options.

Digsby: This desktop app is probably most recognizable for its multi-client IM support, butDigsby (for Windows only) can handle your social network profiles, and manage multiple Twitter accounts.

Web

Matt: Matt, which stands for Multi Account Twitter Tweeter, is a colorful and simple Twitter app that just lets you update multiple accounts from the Web.

TwittBot: TwittBot makes it possible to not only update multiple accounts, but allow multiple people to update the same account. The service looks for @replies to repost to specified Twitter accounts, and bots can be open to anyone or closed to a select group of individuals. This is a perfect tool for Twitter accounts that aggregate tweets from a variety of sources.

Tweet3: For web-based multiple account support that’s slightly different than the rest, there’sTweet3. The site provides you with a dashboard view for each account, where you can customize the color, integrate with Facebook, follow and unfollow Twitterers, and adjust settings. Should you tweet links, Tweet3 will track their performance in the analytics tab.

Splitweet: Designed around managing multiple Twitter accounts, Splitweet is great for viewing a stream of tweets from all your accounts, posting tweets to multiple accounts, and following brand mentions. Positioned as tool for brands, Splitweet doesn’t really deliver on that promise, and companies would be better off with CoTweet, EasyTweet, or HootSuite.

TwitIQ: TwitIQ is exactly like Twitter.com, except function-rich. So imagine your Twitter homepage including options to toggle through accounts, view a keyword tag cloud, and tab through conversations, questions, retweets, and URLs.

Twitomate: A very basic app designed just to let you queue tweets to publish on a rolling basis. But, if you’ve got multiple accounts and you just want to keep them fresh with regular updates,Twitomate is worth a look.

TweetLater: Another web service dedicated to automating the tweeting process, TweetLaterincludes support for unlimited Twitter accounts and bulk upload and scheduling of tweets. There are even some extra goodies thrown in for professional accounts.

Semi-Professional

CoTweet: CoTweet’s already the Twitter CRM Tool of Choice for BestBuy, JetBlue, and Ford, and that’s because it adds a business layer to Twitter account management. Yes, you can have multiple accounts, but the key with CoTweet is allowing multiple people to safely manage the same account so there’s no duplication of effort. We also love it for scheduling tweets for later, assigning tweets to coworkers, and adding notes to Twitter users.

EasyTweets: Positioned as a tool for marketers, EasyTweets is similar to a blogging platform, and comes with a minimum price tag of $24/mo if you choose to upgrade to get continuous searches, support for more than three accounts, post to multiple accounts, SMS alerts, and Google Analytics data on links. EasyTweets has a few tweet viewing options, but TweetDeckfans will especially like the Deck View (columns) of tweets.

HootSuite: A nifty web-based app for multiple accounts with multiple admins, HootSuite is also great at giving you visibility into link stats right within their dashboard view of tweets (so long as you use their ow.ly URL shortener). It’s also a convenient app for Twitter search, scheduling tweets, and posting to Ping.fm to update more than just Twitter.

Browser Add-Ons

TwtterFox: TwitterFox is a Firefox extension from the same guys that are behind the TwitterFon iPhone app. TwitterFox sits within the right hand corner of your browser and does a great job at keeping out of the way. Users can add multiple accounts in preferences and toggle through each of them in a single column view.

Adjix2TwitterLink: This bookmarklet is brought to you by URL shortening service, adjix. It’s simply for tweeting links while you browse, but since you have the option to specify which account to tweet from, and send later, it could prove extremely handy.

iPhone

Twitteriffic: The new and improved Twitteriffic 2.0 is a beauty and an extremely functional, free iPhone app that makes Twitter terrific on the iPhone and manages multiple accounts nicely. If tracking is your thing, you’ll love how Twitteriffic handles saved searches and supports advanced search queries.

Tweetie: The leader of the mobile pack, and the number 3 Twitter client overall according toTwitStat, Tweetie’s ($2.99) multiple account support is just one of the features that you’ll love about this iPhone app.

SimplyTweet: This full-featured iPhone app ($3.99) does the basics and then some. On top of managing multiple accounts, you can view trends, add notes, create saved views of friends (groups), use the Safari bookmarklet, and look up contacts while composing your tweet.

TweetStack: TweetStack ($2.99) brings your TweetDeck columns to the iPhone, and unlike TweetDeck, supports multiple accounts. Pick TweetStack if you want a customizable tab bar, groups, search, and retweets.

LaTwit: A multi-account Twitter client ($2.99) for the iPhone that supports posting to Ping.fm, the option to hide users, custom font sizes, and interchangeable tabs.

More Mobile

Gravity: A native Twitter client for S60 devices (Nokia, Samsung, and LG phones), Gravity costs 10 bucks and works wonders for multiple accounts, Twitter Search, a tabbed view of your timeline, replies, messages, and friends, as well as groups, and multiple photo upload options.

Poketwit: This app is for Windows Mobile users and is perfect for multiple accounts, groups, conversations, retweets, tweet shortening, and having a Twitter address book.
