I left the web hosting business in 2008 and came back in 2013. Prior to 2008, there was a little wordpress, but there was b2, b2 evolution, MovableType, and a lot of the landscape was Perl based.

I rejoined the ranks in 2013, and holy smokes. WordPress. WordPress everywhere. It's even more so now. These days, to be in Web Hosting is to be in WordPress Hosting.
