What's in a Name?

I have been wanting to start a blog for a while now, but I could not think of a way to begin.

I decided just to start one and hope something came to me, especially since I had about three hours of nothing to do while sitting in front of a computer at work (I know the title says I am unemployed, but I don't really count 20 hours a week of mindless work as a real job).

It wasn't until I had to enter my name that a topic came to me. What name should I go by?

I don't mean in my personal life because I don't think I will ever be anything but Bobby, as childish as that sounds. I don't mind being called Bob, but introducing myself as Bob just sounds weird. As for Rob or Robert, I don't like when other people call me those, let alone referring to myself as those.

The problem is every time I read Bobby Callovi as my byline, in introductory e-mails to potential employers or at the top of my resume, I feel like my credibility takes a hit. Bobby sounds childish, and I hope to be taken more seriously than a 5-year-old.

Even though I have had many articles published as Bobby, I believe it is still early enough to switch to something more professional sounding. I just don't want to be still thought of professionally as Bobby when I am 50.

I have asked some of the people closest to me what they think and have gotten mixed thoughts. I hope to get more responses with the blog, so please give me some feedback as to what my byline should be.
