This is a neat “browser in a browser” Ajax application. It makes Wikipedia beautiful, simple and lovely, almost more like an OS X dashboard widget application than the gigantically time-sucking wonderful website that it is. Beautiful.
Neat use of forward / back, nicely designed. As nice as this is, I don’t think I’ll be switching from using Google to find articles in Wikipedia anytime soon. But this is a really really neat and clean way of searching it.
It would also be neat if it could be pointed at other data sources / web sites than just Wikipedia.
By the way, the tranlsation editor seems like a great way to do that. Instant translation of the strings…
Gollum is GPL, and it looks like the source code will be available soon.
