By the way, I made one for Telegram, if you use that:

I posted it but not many people seem to use Telegram, or find it useful?

I guess not so many people use telegram.

And email somehow fits better the calm pace of discussion here on HN.

I agree, it was just too many clicks to reach my inbox for me, so I made that instead.
