Since Matt is looking at several changes/improvements, I though I'd mention one I've wanted for a long time -
Read vs Not Read
Each day we have a different amount of time to read new blog postings, and each day there's a different volume of blogs posted, not to mention that some take a long time to read through, read the comments, and visit all the links.
Whether in Featured Posts, Associates, Groups, or any of the headings on the Dashboard, I'd like to see a button we that would bring up all the posts that we have NOT read. Once days go by, good posts get lost.
