Is 140 characters just never quite enough to convey the entire meaning of your Twitter messages? Worry no longer – Tweetdeck has unleashed, a service provided within Tweetdeck’s platform that allows Tweetdeck users to tweet to their heart’s content without character limits. Messages longer than 140 characters will be available for all Twitter users to read.

Tweetdeck users can compose tweets longer than 140 characters by upgrading the Android or Desktop versions of Tweetdeck,  or by accessing Tweetdeck via Chrome (iPhone and iPad upgrades are coming soon.) Tweetdeck users can then tweet beyond the 140 character limit using, which works by creating a special web page containing your full message – similar to services like Twitlonger. A short version of your tweet, plus a link to, is posted to Twitter. Anyone using the TweetDeck apps for Desktop, Chrome or Android will be able to read the full text of the message directly in the app. Anyone else will be taken to a FriendFeed-type page on to read your extended tweet, or “Long Post,” where anyone can comment on your tweet using Disqus.

For TweetDeck desktop users, updates will be shown as double-height cells in a TweetDeckcolumn. If the text is longer than can be displayed in a double-height cell, there will be a “read more” link at the end of the tweet. Chrome users of Tweetdeck will see long updates as auto-expanded inline with no further clicks or popups required. Basically, they will appear just like normal tweets, only longer, and you can respond to them as you would any other tweet. Android users will see long indicated by a […] icon in timeline view, but opening the detail view for one of these updates will show the full text. Like in the other apps, you can reply or retweet as normal.

But will other Tweetdeck users really want to see an entire blog post in Tweetdeck? A 318 character tweet – only about twice as long as usual – takes up nearly half of a column in Tweetdeck. I can safely say I will go crazy if every person I follow decides to abandon brevity entirely, and only moments after @jakeludington tested the function (above), his followers were already rejecting the concept, asking him to “never do that again.” Tweetdeck’s idea to integrate “long posts,” in an effort to build a larger and more devoted user base, could actually backfire entirely.

It is also important to note that, according to Tweetdeck’s blog, any message posted via will be publicly visible at the specific address included in your tweet when it is posted to Twitter. There are NO private updates – so even if your account is protected, a tweet will be public.

Would you post or read longer tweets using in Tweetdeck? Or is Twitter best when used with brevity – in 140 characters or less, as it was designed?
