Usability did it.

You download an exe, install it, make an account and it runs. Just like that. Everybody can do it.

There are tons of useful and great software out there. Most of it is not easy for the public. Some (most?) of it doesn't even have an GUI. People rather sell their identity and even pay than suffer through too many hops.

Not even a EXE. The web version is feature-complete, so you only need to click a link.

You're right. I forgot about that.

I also forgot all those people who came from the TeamSpeak servers.
