I agree with you. It's better to have good than random campaigns. Before, what I did was to pick the campaigns on the first page of the bounty thread, and hope that it will pay in the future. I did not bother to get more information on the ICO, but now I learned it the hard way, by which out of all the campaigns I joined in the past, only around 10% were successful.

I'll follow what is stated here and try to get better campaigns.
