Why are there no -1's

[mrghost]

I don't think I've seen any -1's on this site. It pisses me off when people don't leave feedback though.

I've actually stopped leaving feedback because the last few instances I left positive feedback and received nothing back. Don't know if it was because I smelled that bad, they are lazy, or maybe some people just don't "do" feedback, but unless the transaction goes badly, I don't want to bother anymore if it's just going to be me posting.
