I find Discord to fill this space in a slightly more effective way, although I don't believe they differentiate from mobile vs. computer use quite yet. However, I find a majority of my friends (and I personally) use discord mainly on desktop. I don't even have discord on my phone.

Discord has absolutely replaced AIM/MSN/ICQ/IRC for my friends. Everyone I care to chat to uses it, and has it on all their devices, including phone, as our primary messenger. My circle of friends is admittedly nearly entirely techies (and some finance crowd who seem to love Discord too).

I use Discord, but I only have it installed on my phone. More convenient that way.

Do you actually use it for gaming?
