I've tested it and it works, absolutely amazing, though not without a downside, and the downside is that, one would have to keep this in their Browser tab at all times, or bookmark, which is one.
Second downside is that, this is not really a notification since one would possibly have to visit the tab, refresh it to find new replies, quotes or mentions.
On this note, I would still prefer the telegram bot since I get a real notification even while I am not on the app but have my internet connection on.
For those who do not use telegram, this is definitely a good alternative, but for those of us who use telegram, the altcoinstalks notification bot on telegram is much better (my personal opinion).
