I want to change the URL for my blog, but I don't want to go buy a new website and transfer my stuff over and deal with all that nonsense. I'm fine with it being a .wordpress.com url, I just want to change the first part of it. Right now it's meggomyeggo89.wordpress.com and I want to change the "meggomyeggo89" part to something that reflects the subject of my blog a little more. How can I go about doing this? Am I really going to have to buy a whole new domain?
