In reply to Steve.

… doesn’t Lynda suffer from similar problems, particularly when it comes to being uninterested in the community? What was the last WordCamp that Lynda sponsored?

I don't think so. Lynda's WordPress courses are a tiny fraction of what they offer. I have memberships on both sites, and similar to Treehouse, I wouldn't maintain a membership at Lynda solely for the WP courses (even though they are great, in both cases).

Even though it'd be nice, I don't see any reason why Lynda would feel obligated to sponsor a WordCamp.

FWIW, when it comes down to bang for the buck, Treehouse vs. Lynda - - Lynda is by a long shot the better value. You can learn about anything there - sound design, web development, audio production, photography, video, animation, graphic design, drawing, lighting, accounting, Quickbooks, object oriented PHP, and yes, even WordPress. :) And, pretty much all the courses are quality.
