I go to "threads"* first. I check to see if someone has replied to me since I was last here and if it needs a reply (or at least an upvote). Then I typically hit "comments" next. A good comment is very often what draws me to the discussion page for an article. After that, I check out what's "new". If it's a big yawn, I will check either "ask" or the homepage. Actually, I have been known to scroll down to "lists" and check "most active" before I bother to go to the homepage. I really spend relatively little time on the homepage.

* For some bizarre reason, my bookmark has defaulted to someone else's threads page, so I actually start there. Sometimes I read their comments before going to my own threads page, sometimes I don't.
