Thank you for providing an example. It's not a "bunch" but still. Could you explain why did you use word "regrettably", is it a bad thing these projects exists?
Other related things are fine: e.g. mapping public keys to human-readable identifiers like a nickname is a good match to what a blockchain is good at, I get why people like the idea of cryptocoin-payments in a messenger platform, ... Still leaves the general concern of "does this really need it's own coin with an ICO and hype", but at least the ideas make some sense there.
