Heavy-duty social networkers will be familiar with the name “Seesmic“, a desktop and web Twitter client. It has officially gone mobile for Android and BlackBerry, with the expected features such as home screen notifications, picture sharing, timeline viewing, saved searches, and basic tweeting. The one thing I haven’t seen elsewhere on a BlackBerry twitter client yet is lists support; more specifics can be found on the BlackBerry page. The Android version has a few cool tricks, like saving tweets as drafts and video sharing, but to get a closer look, check out Seesmic’s Android page. To get downloading, point your mobile browser to seesmic.com or find it in the Android Market.
