DanielBMarkham: Pick any of these you like:1) Ordering of articles by comment activity instead of votes2) Ordering of articles by hits on a RegEx expression (which would persist between sessions for each user)3) Listing of who's online now (reads/comments in the last 15 minutes or so)4) Photos in the profiles5) E-mail alerts when somebody responds to a comment I've made (for extra-cool points: allow email replies to auto-post)
