[liberationtech] About Telegram

[sam de silva]

Hi there,

So it's almost a month since this thread died.

To me, it looks pretty good and while I am not a mathematician, Telegram looks like a good solution to help improve digital security.

But this list has the experts. What's the recommendation? Was there any consensus about Telegram. 

Thanks and best, Sam.
