Not the widest audience, but the most receptive/interested audience, yes. Even hashtags don't really work, as they're so spammy and most people don't use them, and if everyone is only looking at the trending list, and you're not trending, then they literally don't see you (even if they follow you).
Most of the users on here have never seen anything I've written. Since I often write about obscure/niche topics, this is a real problem. There's currently no way for me to just ask if there are other people who want to talk about Tibetan philosophy, or whatnot, because you have to see me asking to answer the question. Catch 22.
I'm essentially "forced" to write about Bitcoin, in order to get more visibility, so that I can then ask the new followers, if they are also interested in Tibetan philosophy. It's algo-driven writing, basically, like the way people on Instagram were all obligated to have at least one BLM post, and then they had to have a #metoo post, and etc.
I'm hoping relay-communities and better algos fix that, but the vote's still out.
