Yea, twitter was a poor platform for scientific discourse (honestly it's not a great platform for anything other than mediocre memes) I guess it was that way just because people were already on it. I'm hopeful platforms will spring up which provide more fruitful discussions. I'm not sure if mastadon is it, but it seems to be pretty good so far (smaller, but more focused user based, plus decentralization is always appealing for some ML folks who are into the crypto, less control sort of stuff).
