All communication with Twitter and Wozai now handles retries up to 3 times.
Especially Twitter sometimes gets communication hiccups due to overload, so retries are now done to secure that updates and user information requests succeed in most cases.
The home and Timeline pages now show the most popular messages. Views are counted on the landing pages only, not on the home or Timeline pages, to avoid skewing.
Right now there’s no degradation of popularity due to message age, but that’s considered to favor newer messages (similar to how Digg works).
All scaled content pictures (or thumbnails) are now cached, so they don’t have be scaled every time they are viewed. That should result in better performance on the home and Timeline pages.
Pictures on the landing pages are still scaled in real time, but that might change later.
