I actually liked the article because I used to be confused about the fact that anyone would choose this limited protocol over RPC but I'm starting to get it.

I personally will still stay away from it. I'm sure that if I implemented RESTful system, eventually I would need some special functionality that would force me to either emulate RPC over REST (what was the point implementing it in first place if I do that) or end up with 2 interfaces - one for REST and other for RPC, making things confusing.
