You're right, but you'd need your own specific Telegram-internal user id so that your message will only be routed to your specific chat. With my little piece of code, n people can register at 1 bot. Without it you would either have to figure out your user id first or have n separate bots for n people. Of course, the advantage is not too dramatic ;-) And yes, the ability to link the bot to further services than only Telegram is another plus.

You can get your own (or group's) chat ID with @get_id_bot, if you don't want to just get it yourself via `getUpdates`.
