The only thing I'm trying to avoid is getting my screen name as a search result in a search for my name.

Anything else I don't care about at all. If someone is determined to stalk me, hiding my information won't help very much. I refuse to be so worried that someone might stalk me, that I start to question all my online activities and if I'm giving away too much information. I'm not shouting at the top of my lungs "Go there and stalk me!" but I'm too lazy to think about the possible implications of every little thing I say and do.

Of course I don't think I'm interesting enough to ever acquire a stalker.
