I've been mulling over an idea for a webapp to help people make better use of their twitter favourites. I use my favourites to save things I want to see later, need to remember to reply to and tweets I find amusing. How do you use your twitter favourites? What features could help you use them in a more effective way?
I personally do not use favourites. I have friends who use them in conjunction with <a href="http://faavorite.com/" rel="nofollow">http://faavorite.com/</a>. It might be worth checking out that site to see how your idea differs.
