The more energy you put into being anonymous, the more anonymous you are, but it's not an on or off switch. It's like something that can constantly be improved. You can even go as far as changing the way you speak to avoid stylometrics.

The question to ask yourself is 'what can reasonably be found out about me?' You can be found on the smallest trace of evidence, but is it reasonable to expect someone to do that? You're not exactly a government spy. Just take obvious steps like not using your real name and you should be fine.
