I thought Twitter was in a death spiral, is it still good for finding an audience?
Also, do you have an opinion on Threads? I tried using it but they currently don't have a tagging system so discovery is kind of difficult...
Twitter is still good, mostly because my target audience congregates there. But if I were to start again I definitely wouldn't choose it.
Tiktok is 100% the way to go, no other social media comes close. Figure out how to translate your content to video - gameplay, workload, tips, day in the life of a dev, etc - and just stick with it.
