In reply to Dave.

I guess it’s just a business decision and a symptom of us all being too cheap in the WordPress world

That makes no sense, at all.

Treehouse isn't a WordPress specific learning site. I don't imagine that too many people sign on there solely for the WordPress courses, or that Treehouse would expect their WordPress offerings to drive a significant portion of their revenue.

It does seem silly, on the surface, that they'd drop their WP offerings but like Peter mentioned, it's likely due to overall interest and is without a doubt driven by the numbers.

Treehouse definitely doesn't have the reach and diversity in their catalog that Lynda does, and they don't seem to specialize in any one thing. The main things, to me, that set them apart are their quizzes (which honestly are pretty annoying to me) and their community forums.

I'd guess they are having trouble differentiating themselves in a crowded market space and looking to double down n the areas that are driving the most revenue.

Personally, I've had a Treehouse membership for a few years now, I don't use it for WP learning.

None of that is meant as any sort of negative reflection towards Zac, he's a smart, talented dude. I'm sure he will land on his feet.
