Seeing all the bleh posts lately, wanted to say all went seamlessly on a new 2.9 install. Even got the Akismet and a Captcha plugins workin' fine. So, it can work.
I think many people have two issues:
1. cheap azz hosts that suck.
2. zero knowledge of how to Webmaster.
I've been doing web stuff since 1996 and run on a powerful Reseller Host...it helps a lot.
Both of those can be remedied though with a little research and effort.
thx WP, gr8 software.
