My own personal work was interesting enough to others that the right people shared it and I ended up with some major executives and founders in tech following my small account just because they found my work interesting. I also got many job offers just through sharing my work and having positive discussions with people.
Now so much of that is destroyed. The algorithm rarely surfaces novel and interesting things from people you don't yet follow, it instead surfaces blue-check accounts trying to be full time influencers. If a large account posts something you can't add insight to the conversation because your comment will be far below blue check accounts responding with arbitrary nonsense for engagement farming.
Many of the most interesting people on the platform have bailed out because there's just so much toxicity and distracting stress tolerated on the platform now, and no way to self-moderate it beyond ineffectually banning individual accounts.
Twitter was imperfect before Musk, but still extremely valuable in my circle. Now I feel Musk views the platform primarily as a way to manipulate social and political outcomes rather than a place that enriches its users.
