Regular reminder that Telegram's encryption protocol, MTProto, is not secure, and you should not ever rely on it for privacy. Use Signal or WhatsApp instead.<p><a href="https://eprint.iacr.org/2015/1177.pdf" rel="nofollow">https://eprint.iacr.org/2015/1177.pdf</a><p><a href="http://www.cryptofails.com/post/70546720222/telegrams-cryptanalysis-contest" rel="nofollow">http://www.cryptofails.com/post/70546720222/telegrams-crypta...</a>
What I thought was more interesting was the ability to send money to Telegram bots. Maybe they are trying to take on WeChat as the "everything" app.
It's amazing how they entered the dense market of messaging apps and with superior UX, native clients and a bit of luck(brazil banning whatsapp for couple of days), they managed to get 100m MAU.
Telegram is definitely the most feature-rich, customisable messaging app out there.<p>The stuff you can do with it is amazing. Aside from having a true desktop client not dependant on your phone, I've set it up so that I receive my favourite comics(XKCD, Dilbert) when a new one releases. I can also see and delete my mail through another bot, and I can get sport scores too.<p>The new instant view also opens up links immediately without loading times(Medium a few other sites only so far, but most major websites are apparently coming with the new update).<p>It also allows you to quickly go to any date in a chat you've had with someone else(What did you talk about on 2nd June 2015?) and it has a self chat feature which is essentially an unlimited cloud service. Since you can upload files unto 1.5 GB, you can store links, photos, text and files in your self-chat, and have it available on all your devices.
