With the advent of the WordPress Answers Stack Exchange site, there's undoubtedly going to be overlap. But I just want to get some advice:
I'm a developer and I kinda hate WordPress, but have to use it occasionally. My WordPress questions are usually development ones (when I have them), and most often related to 'how WordPress handles things', which are pretty obvious in straight programming terms. But with the WordPress layer of abstraction, they become problematic.
I find that most developers that have gone near WordPress are usually also PHP/JS/CSS/MYSQL guys who dabble with WordPress and, as a result, hangout more on SO. And theres a die hard bunch who are heavy into the WP.SE site, but generally the WP site is for people trying to muddle through the day to day operation of using WordPress and its many themes/plugin etc.
As a result, if I were to ask something pretty in-depth about writing / integrating new & strange features or something, I'm talking to a much smaller group of devs than I would be on SO.
So, enough of the ramble, my question:
Should I be posting heavy development questions relating to WordPress on the WP.SE site or to SO? Can I post to both, or is cross posting frowned upon in these cases still?
