I found an interesting paper describing the 25 possible motivations for clicking the “Favorite” button on someone’s tweet:
The team that came up with the fav button probably did not anticipate all of these uses. I’m guessing they probably thought of 3 or 4 at most.

I wonder if Facebook’s “Like” button has similar connotations. I’d like to see a study comparing similar functionality across multiple social media sites.
