I like reading profiles, not because i'm weird or something, but because I like to find out about people - I'm a genuinely curious person. I do like a profile that is comprehensively filled in, lets you find out enough information about someone in order that it becomes easier to strike up a conversation with someone.
I do believe, though, that you shouldn't put every detail into a profile, otherwise, what are you going to ask someone when you start talking to them? However, like anything you read online in forums, it's important to remember not to believe everything you read, at least not until you have gotten to know someone first.

Behaviour breeds behaviour - treat people how you would like to be treated yourself
