Hadn&#x27;t heard about it. Just checked it out, and it looks interesting. Unfortunately, due to network effects and my social circle, 99% of the people I know pretty much only use either Wechat, Facebook, or e-mail, but I look forward to seeing something disrupt this space with something better, more functional, cross-platform, and multi-login.<p>It would be killer if Telegram could interoperate with at least 1 or 2 of the other services, which would allow it to ramp up adoption. Unfortunately Wechat is very insistent about not allowing 3rd-party applications to use their messaging protocol, and Facebook seems to have closed their XMPP interface as well. I would guess Whatsapp probably has the same attitude.<p>In this respect I really, really miss the days of Pidgin and those other similar applications which used to be able to put MSN&#x2F;ICQ&#x2F;AIM&#x2F;QQ&#x2F;Yahoo&#x2F;Zephyr all on one interface. That seems impossible with the state of mobile apps now.
