I'd love to find ways to collaborate with anyone who's interested :) I also forgot to mention that you can download an export of (most) of the timeline events from http://endlessorigins.com/ -- I update it from time to time with new events, too. To my knowledge, it's the largest freely available structured data set of historic human events. Could that be useful to you?

That looks great, I am going to look into this at some point. Thanks a lot for the link and all your hard work.
