I do. Often. I prefer a 5 star system based on this:
1 star: just bad 
2 star: meh
3 star: ok
4 star: good
5 star: excellent

Given my original use case for this, books, a 5 star system is pretty much mandatory, IMO. 1 is not enough as it just signals that it's of interest, but not WHY. Three is better as you can indicate positivity, neutrality, or negativity, but nothing more. Ten stars is dumb and I have no use for it. Therefore, I prefer and will always advocate for a 5 star rating system for books. Other types of media are fine with a 2-3 indicator system. (Old school thumbs up/down are useful, and effectively a 3 indicator system given that you would have to really like it dislike something to bother with giving a thing a thumbs up or down.)
