That's pretty cool. I built a backend with titles list etc. It seems in vain now. Hehe :). Any suggestions to make stumbling Wikipedia more meaningful?
When you use Wikipedia's own system you get some really inane pages with statistics about minor towns or the like.. but I'd rather hit a button and get something that's either curated and known to be good OR that other users of your extension have voted up in some way.
Another thing that might be handy for something like this long term is making sure I don't see the same page more than once. But that would be a lot more data for you to store.
