@Steve These are legitimate questions. I don't have an answer for you, as I honestly have no issues with the current commenting system in WordPress. The default could obviously be a bit better, but it's simple enough, it works, and it's easy enough to extend it through plugins and the different filters the comment form offers.

But if you have ideas for improvements, or find bugs that should be fixed, I'd suggest opening tickets on core.trac.wordpress.org. You'll see if others share your opinions, can reproduce the issues, and are interested in improving the current system.
