I was on it for about 2 years. Very toxic, had to exit stage left.

I don't even know how to use twitter.

The level of toxity depends on how you use it, just like all other forms of social media. If you like to be involved in heated arguments, you have to play by those rules. If you just hang with online friends sharing the same interests, you can get by quite well. If you don't make any friends, you'll be tweeting on your own as long as you don't tag others.
