Well, out of the desire to get to this rolling I put something together. At this point specific keys and clinical methods with controls, etc. may not be the focus. It's probably more about what Colin said: "'an edge', a probability that certain techniques work better than others, and a probability, say, that mass spamming directories has very little effect." Though if someone wanted to run a specific test (or several) and dole out the tasks, that should work too.
If you want to actively participate (shared specific data, urls, etc. should be a two-way street), send pm. If you don't have time to participate, don't sweat it, you won't be missing out on anything as we plan to share general findings in the IC.
