Should I move my blog

[Ms Naughty]

I posted this in the SE forum but no-ones paying attention so I'll ask the blogging people

Do you think it's a good idea to move my blog to its own domain, even though it's got a heap of links to it? The blog consistently appears at the back of the index thanks to a penalty of some kind that I can't fix, so all those links don't help me.

And, on a technical note, is it easy to move a WP blog? Surely it's just a matter of pointing the new blog to the existing database and then removing the old files. Lots of 404 errors but maybe I can do a 301 redirect for that?
