Sorry I didn't respond to that. No, I'm not associated with Telegram in any way. And I'm not crypto professional :)
I totally understand what Telegram critics are saying, but in every article there's always a note "Please use TextSecure, don't use Telegram". By how it looks, it seems to be a way to market TextSecure and not to discover Telegram's security flaws. And critics rarely respond to Telegram team's comments where they say that the claims are wrong.
