Seesmic is launching a new experimental version of its video social networking site, at this separate address: http://new.seesmic.com. Drawing on feedback (requests, suggestions and complaints) from its user community, the Seesmic test site keeps a lot of the functionality of the original application, but with these new features, among others:

-Smaller Flash load, “except in the player”.
-White, not black, background (Illuminates your face if you’re recording videos in low-light situations.)
-Auto-refreshing timeline
-Videos now play in the thumbnails (you can watch them without having to leave the timeline)
-User and video search (plus you can bookmark your searches)
-New user profile pages
-Multiple privacy posting options
-RSS and Atom feeds for public and user timelines
–Cooliris view. Seesmic is working with Cooliris (formerly PicLens), which transforms your browser into a full- screen 3D experience for consuming online media.

Additional features from the old Seesmic that are being added quickly:
-Posting YouTube videos
-Language filters
-Upload a video

The company asks that users poke around the test site and tell them what you think.
