Although Seesmic has been around on BlackBerry for a while now, I'm guessing the constant onslaught of RIM in the past few days may have helped just a little with triggering the blog update from the Seesmic developers. As posted on their blog:
Effective June 30th, Seesmic will discontinue support for Blackberry in order to focus development efforts on our most popular mobile platforms: Android, iOS and Windows Phone 7.
We encourage those effected by this change to try out Seesmic for Android, iOS and Windows Phone 7, as well as Seesmic Desktop and Web.
Ouch! Personally, I've never been a user of Seesmic on my BlackBerry -- I always felt their BlackBerry efforts a little underwhelming and I really can't remember the last time I saw a Seesmic for BlackBerry user in my Twitter timeline. That's not to say they don't make great apps because they really do, Seesmic is my preferred Twitter app on Android but for BlackBerry their offerings weren't all that great. Any Seesmic for BlackBerry users out there going to miss the support?
