Sweet! I think I prefer it this way. Thanks for the update.
I've mentioned this idea before, but I'll bring it up again for sake of discussion. I think manually setting personal tags should be done away with, and users should be able to follow any combination of @user/#tag/.domain that they want (including all three in one follow). This would simplify the submission process slightly (since one wouldn't have to think in terms of personal tags and whether they'd like to use one), and give more flexibility in what a user can follow. I have no idea how feasible this is with the site architecture, but I think it'd be really cool to have.
