Lol! I don’t know about wrath so much as complaints re: the headache it would have caused me. I’ve played with Squarespace myself, and investigated it pretty thoroughly for clients, and ultimately I stick with WordPress for the same reason I like PCs better than Macs (and I build my own PC as opposed to buying one from Best Buy): I can do whatever the hell I please with them. Sure, sure, I may never -need- all of the extra features or potential, but I like having the option. Proprietary, turnkey systems can get limiting and very annoying at unexpected moments.
That said, of the turnkey blog systems out there, Squarespace is one of the better ones — and they know their market well enough to tier their pricing in such a way to make some good coin, too.
