An update, Feb 2023: I think it's time to start this process. Many social media platforms are based on advertising. As such, they gather data and profile you for advertisers (spit) but also limit your reach unless you pay. This has worsened over time. I have over 2,000 followers on Twitter (I created the account in May 2009). Do you know how many people Twitter shows my posts to if I don't pay? About 20 of them. So 99% of my followers don't even see the updates I post there. So what's the point?
As such I will focus on my newsletter (which people can reply to, to contact me directly), and Discord (which doesn't include advertising, and is much chattier - I have a server there for fans and fellow authors). I hope some people will join me in both.
