Most of the people disagreeing seem to be forgetting that public doesn't necessarily mean using your real name. We used to have vibrant communities full of people with names like "claxxon" and "zerg". claxxon knows about cisco networking and zerg knows about the best punk bands in the chicago area. Their real names? Not needed, wanted, or relevant, and we're offended you even asked, noob!

I try to live up to that ideal in a way. I'm more comfortable with my internet handle than my real name. However, connecting the dots between a username with any decently long history and the person behind that username is trivial unless you go out of your way not to reveal too much about yourself, and even then, given enough time, there will be enough breadcrumbs eventually.

I've given up on preventing people from connecting the dots. If people want to engage with me, they can do it with my username in situ, or send me an email which uses that same username. If they're being creepy about it, I can block them and ignore them.

That use to be useful in a time where it was much harder to instantly de-mask those handles.

If you're trying to make a name for yourself and you're social long enough, you'll eventually have a decent sized footprint on the internet. Sites and services get breached all the time.
