A Prose by Any Other Name -- veinglory

At some point everyone has to decide whether or not to use a pen name, or several. I would be interested to hear from authors who have been published for at least a year or two on whether they think the made the right choice, the up- and down-sides of the name they chose.
In my case I am glad I chose to use a pen name. I ended up in a moderately serious sort of job where I wouldn't want the subject of homoerotica to come up with every casual Google search. I must say though, with my first trade paperback novel coming out there would be more offline avenues for promotion of I was doing it as 'myself'.
I went with a relatively, well, silly name. But on the whole I think that worked out fairly well too. I get a lot of hits to my website from people googling for my pen name so I am thinking it is somewhat memorable. A few people get a wrong by spelling it correctly, but on the whole it has worked out.
I am still toying about whether to use a second pen name for MF but on the whole I probably can't be bothered. Keeping track of two personas is keeping me busy enough....
