For a while I've been considering purchasing the
Blog addon for vBulletin. You can view a demo here:
vBulletin Community Forum - Blogs. It would allow you, as a member, to create your own blog page and talk about anything you like (preferably programming). The only question I have is: "
Will anyone use it?"
I'm not a blogger myself so I doubt I will use it much. Will you use it? Will you create a blog under your username and actively blog in it?
