As for WP support, that's a different kettle of fish, one that I've complained about. Search my profile posts. I rate it a solid "meh". It's not bad, but it's not great. Could be better.
wordpress support is only as good as the people that reply. If youre not pitching in, you cant really complain.
Thats not me pointing fingers at anyone, i'm just saying..its kinda like people that dont vote, ya know?
way too many people come here and assume, incorrectly:
1. that moderators have special powers, or are being compensated to provide support
2. that wordpress guarantees some level of support that is provided on these forums.
Neither of the above is true.
As it stands now, and of course, things could change next week, support around here is user driven, like nearly every other opensource project.
