I posted some questions about WordPress development on my site (please feel free to leave a comment here or there with any answers/insights).
I'm a web/app developer, and I spend most of my time working in the Drupal community, though I hear many good things about WordPress, and I have helped a number of people with WordPress sites. I have no ill will towards either development community, and understand there are differences—99% of the time, if I find something that upsets me in any development community or project, it's not because it's wrong (necessarily), it's just that I don't understand why it is the way it is...
That said, I was wondering if you have any good suggestions as to the best way to ingratiate myself into the WordPress development community/ecosystem. I don't plan on becoming a strong core developer or anything like that, but I've found there are many helpful things one can do in other development communities to make sure they're doing things 'the right way' and helping improve things.
For example, in Drupal, hanging out in the various
#drupal IRC channels is a great way to meet some of the smartest and most involved Drupal developers. Going to Drupal user group meetups puts faces with local developers' names. Following Drupal project issue queues is much more enlightening than reading through project documentation (which is often outdated) or browsing Drupal's forums (which are almost a ghost town for many purposes).
What are some of the 'insider tips' for getting to know WordPress? Many Google searches lead me to conflicting and outdated information about different WordPress coding techniques, APIs, etc. I already follow Matt Mullenweg's blog, but he (like Dries Buytaert—Drupal's founder) doesn't often get into technical info or good summative posts about the 'state of WordPress'. Is WordPress Planet a pretty good source of info as well?
