But one of the advantages, as you said, is having the chat on the web & on the go. So I installed it on my phone as well. Wouldn't hurt having some keyboard-related chat and pictures with me when traveling
If anyone enjoys web apps, I use a small program called Rambox which is essentially a wrapper for all kind of web apps, with system-wide notifications and support for a ton of services.
That way, I have Steam Chat, Twitter, Whatsapp, Facebook Messages and now, Telegram, all in a tabbed interface on my work machine.
