Definitely, it was actually pretty simple once I figured out what I was going to do. I started from the link graph put together by Henry Haselgrove (http://users.on.net/~henry/home/wikipedia.htm) that I found when looking through the EC2 public datasets. I then had a few easy steps.
1) flip the link graph from outgoing to incoming, so from any page I can see what links to it.
3) loaded the data into a large binary file that I divided into indexed parts that I compressed and uploaded to appengine to extract and load into bigtable (this took the most amount of time! both to run and to write the code to make it work)
Well, that's more than a lot of people can say about certain projects!
Want to give us a run-down of how you put it together?
