I organized my bookmarks (threads I've started, I suppose) by "most recent" and it's missing several I've done recently. The difference? They aren't tagged.
Was this a design choice you made? (Only including bookmarks that have "tags") And what's the point of having bookmarks instead of the All Threads? Web Designers for Obama/Biden 08.
In the right nav, under community you'll see a link to "<user's> Threads". This is every thread that user has contributed to. Our bookmarking app is separate from forums, and allows you to keep track of the urls you care about, whether their forum posts, articles in the MSDN library, or a url somewhere else on the internet. In the future, there will be a tab on the profile page where you can quickly see all the users threads, but for now it's just a link.
