I wish for reviews + social. You know, somehow combining the power of the web with the good old process used to find out whether something is good or crap - asking the people you know. A review by someone 2 links away from me is very unlikely to be spoofed and I reckon that even 3 links away from me (this is probably a large enough pool?) would be quite trustworthy.
