I recently tried out Seesmic Desktop Preview and was impressed with what appears to be a TweetDeck clone, but quickly found that it lacked Facebook completely.   Now, with that addition, and the fact that it already supported multiple Twitter accounts, I’ve replaced Tweetie once again.

It still isn’t perfect — no Twitter client is — but it offers quite a few features in a well-controlled interface.  It also seems to eat less memory than TweetDeck.

Things I would change about Seesmic Desktop Preview include making the columns adjustable — even allow the ability to stack lesser-used columns.  Also, I just don’t “get” the user list feature.  I was hoping for more of a group feature similar to TweetDeck. I also miss TweetDeck’s “tag cloud”.

Big points, though, for NOT starting the name with “Tw…”! =)

Each of these apps comes close. TweetDeck combines Twitter and Facebook status updates in one desktop-space-stealing application while Tweetie focuses only on Twitter. But I would love to have them combined.

Can we get the power of TweetDeck smooshed into a Tweetie-sized footprint? TweetDeck has a cool feature that let’s you group people you follow and display them separately — I use it to see “local” posts. But that adds yet another column to the interface. Why do I need a complete column for Replies, Tag Cloud, and Direct Messages?

Tweetie supports multiple accounts and has a much cleaner interface. The memory usage is also much better than TweetDeck. Because it’s a Cocoa app (TweetDeck is built on Adobe’s AIR platform), Tweetie feels snappier and uses some CoreAnimation effects to pretty things up.

With the flurry of Twitter clients — I personally have used twitter.com, Nambu, Twitterific, TweetDeck, Tweetie, Seesmic Desktop, even an Adium plug-in — I have to believe we’re getting close to The Perfect One.
