Oh, of people? How the heck do you intend to measure that? ... if we could measure that we likely wouldn't need the blockchain.

well its not impossible.. a hint, (bip14):useragent..... and bitnodes..
though im not sure why you think knowing just the version type someone has suddenly made having the blockchain irrelevant.. (secretly i know you mean if there was a central means of communications then why bother decentralizing the blocks.. but thats not the point)

was the blockchain irrelevant when searching for nodes was done via IRC.. or dns?

It is extremely tricky to not be gamed and sybil attacked. The best we have come up with thus far is PoW and that is far from perfect. It would be great to roll out some tests on a sidechain and attempt to game them.
