All the chat programs are making all the communication pain in the neck and the only way of communicating that you can rely to are old school phone calls, sms and email.

There is also other side, with email you actually think what you are writting as you don't want to flood someone, with chatting it is all about smileys or everybody would be still using irc, I still need to see chat program catching the amount of irc features (actually I would bet Telegram is just front end for irc servers in backend).

And just to mention this gmail feature, it is just nonsense, it will work in their cough spy.. cough ..ing... email system, immediately when it leaves it, it is probably just a mime header which I will gladely ignore. And self respecting techie shouldn't use the gmail (and should be proud not to use it ;) ) anyway.
