Good idea! Sometimes, if a tweet goes to 3 lines, the next & reply buttons get pushed a little below the footer text, which stacks on top of them. You can still select the top of the buttons, but just so ya know. In fact, just positioning those buttons consistently so you can rapidly scroll through the possible questions would be nice.<p>Anyway! I like it, if you decide to keep developing it with better parsing of questions (identifying and removing rhetorical, etc.) and show "other replies" below the actual question to show if others have attempted to answer already.<p>Also, also, I saw someone on your twitter feed suggested you take it off-twitter, but I think the real joy of this is the potential to help a complete stranger who had no idea the whole world was actually listening.
