Well, I have several "alt" accounts; for me it was always a question of whether they make sense.

The account from which I type this is my primary commentary/lifestyle/memories blog that also was my initial account here.

But I also have an account that was created specifically for my artwork, and it dedicated to that only, and never takes on any other content. I also keep a "Cat blog" for our cats... again dedicated to only cat content, because I didn't feel like pictures of cats belonged mixed in with serious "article style" blog posts about life and psychology.
