This is something I found just BS'ing around in the internet, reading up on MMO stuffs. It's pretty old, but it poses a few decent questions. Since this is the Speak to the Dev's forum, I figured I'd post it up. I'm not looking for answers to all of these questions, I just thought I'd post it and you could take a look. Anyways, here is the article.

These points seem especially relevant.

I agree. There are some questions here that require some serious thought to answer fully. Which is why I thought it was important enough to post it here.
