So I'm looking at something like this (
https://bitcointalk.org/index.php?topic=70036.0) to aggregate content into something similar to a Curriculum that would allow the user to get the equivilent of a college course, complete with guidelines and schedules instead of just giving you the firehose of data. One of the ways of gathering the data is a Wiki, so I was thinking about if it was possible to develop a Wiki Crawler that gave out microbits or litecoins every time a significant and helpful edit was made to a page. YMMV on helpful, but it should probably have some sort of guidelines to prevent edit spam for run and profit.
