For a nobody like me, twitter continues to be a good source of news, and fun, if you’ve curated the right people to follow (e.g. catching jokey arguments about burritos between John Scalzi and Wil Wheaton, etc…).
For anyone high profile (and especially women), I imagine it’s a nightmare with all the crap you get. I don’t know how you can get anything out of it when you get hundreds of replies to everything you write and half of it is hateful trolling.
I imagine Twitter could easily let the verified users set their accounts up to only allow other verified users and/or people with old enough accounts and enough followers to interact with them and that would solve a lot of issues. i.e. hellban the new troll accounts.
