I'm sure this is already on the docket but some ideas:
I really liked the Archives on the past Tynan site. Reading through all the old posts would be rather difficult in this new setup.
I noticed there's no website URL for commenter's profile now which is how I came across a lot of other interesting people, would be nice to put in.
The singular emphasis on posts on the frontpage is good for existing users but might be off putting for new people. Where's the About? Where's the popular posts? Aka a sidebar.
