There's a fundamental difference between "centralized, like gmail.com" and "decentralized, like everyone running their own mail server" (which is what what I built, OT, etc. are) and "decentralized, like bitcoin (well, bitmessage, in this analogy)".

I'd argue that gmail is farther from "everyone runs a mail server" than "everyone runs a mail server" is from something like bitcoin/bitmessage.
