I can't go into the specifics in answering your question because I'm not that much into programming anymore, but with the current technologies and many APIs available I would imagine that they are capable of quite a lot. I never really been into mIRCs a lot either.
they can't even play DN well with the crap ISP they have (sadly)
so DN+VOIP would be too much to handle xD
What makes you think that "most of us have bad internet"? That's a rather poor assumption to make, from what I can see most European countries are ranked quite high. So far I haven't heard many players express issues using DN next to Discord either. EDIT: realized you were referring to SEA players, my mistake
Ah yes.. #hashtags.. well as technology advances, things change and we adapt to change, sometimes for the better and sometimes for the worse. From what I understand it was originally created to group (or categorize) items, which doesn't appear to be very different from today. Users do often find now ways to make use of technology though.
