Re: email is so last century
Mailbird isn't too bad. Yes, it has the nasty whiff of Electron about it (I haven't checked if it actually is), but it's usable. On Linux, there's Evolution for those who find ThunderBird disagreeable. The only webmail I use is RoundCube (which runs on one of my own servers).
As for the "bright young things": I thought they all used SnapFarceTwitGram? If you're a narcissistic exhibitionist already, what do you need encrypted communications for? If internet slurp engines can't read and index everything it might be harming your search engine rankings !!! (Hmmm ... business opportunity: SSL/TLS deactivation services marketed as SEO).
