Final Death of Necroposting

The first part of this does not go with the second part since the second part is an opinion of yours. And if you're going to be an owner of a forum you can't have opinions like that.

That would be where you're mistaken. As owner I can frankly have any opinion I want - The site exists to reflect my ideals, just as it did Paul's when it was his. I do in fact dictate the purpose of this forum and all subforums within it.
If I choose to draw the line of what content belongs where that is entirely my prerogative. Blogs are an egocentric successor of forums. They're topical to the interests of the owner, a microcosm of the normal forumscape.

Just because part of the forum existed that sort of served that purpose previously does not mean it will do so in the future, or that it was the ideal way in the first place. Evolution is an ongoing process.

You're welcome to defend why things should remain the way they are - But simply telling me I don't have the option doesn't cut it, because I do. You need to focus on why doing it is a bad idea (and preferrably with better arguments than 'because everyone will leave/quit/hate you').
