I agree that signup should be painless, maybe just an email and verification, but I disagree with the short trial period. Maybe if your application is really trivial, one or two visits will work, but if it takes a while for the value to unfold, say with a collaboration or enterprise product, then the trial period should be longer. I would even advocate 60 days. A group or enterprise product requires a first adopter, who then has to recruit collaborators, and finally has to sell management. You dont want to cut this process short.
