a few things i've noticed recently as the mobile site has been tweaked in past weeks:1. when on the mobile site, i find myself unable to enter into the text fields of forum replies and new posts.
2. there is no way to leave a group from the mobile site
3. the feature that allows you to see the most recent comment in a post when you hover over a link has been disabled for a while on the mobile site. this was an especially helpful feature to have here, although it would usually pop off to the right of the screen, causing me to have to do a tricky hold-down-and-slide maneuver, it allowed me to keep up with recent updates on long threads without having to load the whole thread.
if it matters, i am using an iphone 4 with an un-updated iOS.
