i cant stand disqus, i leave articles more than not because i dont like to be forced to comment using the system. it blows and needs to die... i thing webmasters use it because they are lazy, not because it is good.
I don't know if you've used a lot of blogs/CMSes/etc, but you definitely overrate their commenting systems. Most of them are crap. That's why Disqus is so popular, because it has tons of cool features (like the little popup that says when someone has posted before you).
Heck, Disqus is better than 90% of the forums out there (Hi, there, PHPBB or vBulletin!).
