I already know about
http://www.xda-developers.com, which I appreciate a lot, but which seems to be more device specific. I'm wondering if there is another one that is focused on using the OS and apps, where all Android users can congregate and share ideas, tips, recommendations, evaluations etc.--someplace friendly (like Mobile Read), where the high level users help out the mid-level users, and the mid-level users are willing to help out the newbies; someplace where you don't get insulted just because you asked a question; hopefully, someplace with a useful wiki or FAQ.
Any recommendations? Thanks.
