After a reading session, I click the "Mark Forums Read" link (this used to be automatic...grrrrrr....) to mark everything as read up to the instant. So next time I visit the only bolded threads/posts are those new since my last session.

Keep it to a manageable number of forums and remember the process so you don't re-scan or re-visit threads/posts you've already read.
