A couple of people shared personal information here, and I know of some people here who are easily identifiable via their linked websites or works - including myself. Sharing such information online always comes with a certain risk, but I decided that this is okay for me. The important thing is always to be aware that the account that you use can be linked to your RL - and when you draw the connection to an existing account, you should check if you really didn't post anything before that shouldn't be connected to it.
