Are you lonely? Would you like us all to post complete profiles so that you can decide who would be worthy of contact for possible friendship?

I am a member of several community style websites, and one thing has always held true since the first time I signed up: An excess of information in a personal profile almost always leads to undesired contact, either by too many of or the "wrong type" of people. I don't want to spend my whole time online fending off messages from random strangers, so I keep my information to a minimum.
