Has anything that has built on top of wikipedia as the primary product got much traction? I think it is something that would be hard to really get widespread without it.
Can a 3rd party even maintain a fully up to date set of wikipedia content? Not sure what their policy on scraping is?
Yeah I am aware, but wikipedia changes daily. There would have to be a pretty impressive feature set built on top before many would consider using an out of date wikipedia when they can easily see the latest version.
This dump is updated once a month, though the API is live.
One problem I've found with the dump is that you still need to render it (unless someone knows of another dump) which has caused us a few problems with the current thing I'm working on.
