I'm mildly confused as to why you linked to an article comparing Telegram with Whatsapp...and centered on activism to boot.  It's a complete distortion of the context and addresses not really much that I said.

That said, I don't really care which platform is used.  I just don't think that Telegram is professional, they don't use adequate or proper encryption (which seems like a basic point on a crypto currency forum), and Slack is searchable (which more or less negates the only presented reason for not using them).

I'll be done talking the point though.
