I first tried it just for kicks. But I soon came to realize I'm not one to keep a Blog, and that I actually have a job. Not only that, but I don't read anybody's blog either. And blogs suck, in general.
Also, I want it removed so members will stop clicking on the "Visit %20's Blog" button, it's all empty anyway.
Also, why can't you facilitate it's deletion? Comments by members are not posts. Do they have to stay as site activity, or something?
