I will keep this thread updated with the progress - I imagine it will be about 2-3 weeks worth of results (or lack thereof) to report.
After the case study is complete and all the reports are in I will be grading each gig individually and make available each report from each gig so you can download them and check them all out for yourselves.
I thought this would be a fun little case study to do and I think you'll get some value out of it.
If you want to see the 20 gigs I ordered I've went into more detail in this blog post.
It's a solid mixture of comments, profiles, link wheels, blog posts, forum sigs, and some other stuff mixed in. Could be interesting.
Questions, comments, predictions?
UPDATE Part 2 - July 08:
I have compiled everything here - gig grading, report downloads, and some of my observations on each gig.
Also be on the lookout for my Microworkers and Mturk case study coming next week. It's going to be a doozy.
