Has anyone had an especially good/bad experience with them?
I find a lot of people don't bother updating their details any more - I'm thinking the novelty is wearing off.
It's also a bit annoying the way they suppress email addresses in personal details. At first, I thought it was just a filter for strings with @ symbols in, but now I see it won't even let you say "my email address is firstname lastname at domain dot com." The name gets completely wiped, making nonsense of what you have written.
