Hi,
it would be helpfull to me and probably to logos to have a like button for resources that also displayed the number of users that liked a resources whether they purchased it or not. Also logos could track who liked that resource and they could use the info for target marketing. The logos users could not use this if that did not agree with such a thing. Also being able to state who are your friends like facebook linked to resources they liked would also help me in my decision making on buying resources.
just an idea.
