[Cryptography] Forgotten crypto messengers.

[efc at swisscows.email]

Dear cryptoninjas,

I was wondering what your opinion are about two crypto-messengers who 
often are forgotten and neglected, in the form of bitmessage and 
delta.chat (www.delta.chat).

Have you heard about them, and what are your opinions about them?

I do know that delta.chat say on their web site that they were audited by 
ETH Zürich, so on the surface, that sounds like a strong point.

Beneath the surface, I have no idea. ;)
