I have to say that your names w/ an initial are not only boring and impersonal ( a trend I hope that does not spread) but that it's more than a little like the proverbial dutch boy trying to plug up an infinite amount of holes in the d-ike (oops, another unmodified word the profanity filter won't let you use---who created this filter-- a P.C. religious zealot?) You should worry more about other ways of extracting personal info on the web then from using your full name on this fairly obscure site. There's software, easily available, that would allow one to display your domain, location, the very computer you use, how you use that computer and more. And it gets scarier than that.
In short, there are more important things to worry about (IMHO).
