Get off Aski.

Hello everyone. I stopped by to see what's happening in HeroesWorld. It's 2019, and people have encroached on sacred ground — replacing ICQ as the default messenger [by the way, what even is that?)]

I've been using Slack for about two years. The downside is that in the free version, you can't view the entire message history, you have to pay some cash, which isn't really an option for the common folk.

I've been using Telegram for 4 years, drawbacks: under the desktop version, you can't create encrypted chats, but they're probably not really needed anyway)
The most progressive option, which only Discord can rival. It has voice chat and simple registration, everything you need. But I haven't used it much, so I won't talk about it either.

I'm giving Skype a thumbs down — it's ICQ #2. After Microsoft took over, you could already forget about Skype.

Two pluses. Skype turned into crap almost immediately once MS got its hands on it. An ocean of ads, eats up memory, and yeah, not very stable performance. In short, it's just...

completely unused AIM, MSN, and Yahoo

Most likely, they just never got around to it, otherwise there's no way to explain it.
