1) Consider implementing a system similar to Slashdot where an adjective is picked to describe a post, but also keep the current 5-step rating list. Basically, rating a post takes two steps. First, select from the current list (Awful - Excellent). Add a second drop-down list with adjectives like Funny, Interesting, Insightful, Flaimbait, Redundant, etc.
Make the most used adjective visible with the post's rating, and if you click it, have it show the adjective and rate history. There is no need to show the name of the person who did the rating to a normal person as abuses should be readily apparent. This will stop people who complain about rate-downs where a person never posted why they disagree. A positive or negative identifier could be applied to each adjective to stop people from rating something awful while describing it with a positive adjective.
2) For crying out loud, make my chosen title ", Defender of Justice." "Sarlos, Defender of Justice" makes way more sense than "Sarlos Defender of Justice."
3) Allow users to make comments on their bookmarks. It would be nice for me to be able to remind myself why I bookmarked a certain post or thread.
