I went to begin implementing user blogs when I realised it's already there, just in a less accessible way.
Basically the only difference between a forum and a blog is that in a blog, you can read the post before you click the link to that post. A blog with comments is just a forum, in essence.
So all we have to do is tweak the search system to provide essentially what a blog would provide.
Now, if you go to your profile: memberlist.php?mode=viewprofile&u=282
you can view your blog. It's just a different way of viewing your posts in the Development Blogs board basically. If you've ever added a development blog post to a game it will appear there, or you can make orphaned individual posts straight to the dev blogs board.
That way your "blog" content appears in a blogroll.
Any thoughts on how this could be done better?
