have a section to your acount page that shows projects you would most likely enjoy
this would mean a page showing ideas similar to ideas you have already supported, or contest entries that you have liked. I think this would help since I think that people probably spend a lot of time looking around at other people's projects, but not really finding the sort of project they like. This would also help boost a projects visibility. This would shorten the time wasted surfing the millions of submissions that certain members just might not like.
Yes, and it could be based on the taste of people who proportionally support the same projects as us?
