So I have to resort to clicking about to manually search for my hashtags. Which yields better results. But then I'm missing the stuff people don't tag (which is a lot).
So yeah, it's very difficult.
I'd also say it's all very time bound. Posting stuff while America sleeps means you're posting into the void, because those posts aren't surfaced by an algo in the morning. A tactic I've often used there is to boost my own posts to give them a second wind.
@charlesroper @kissane The world is a big place, and not a "void". If the US is important to you, certainly, time your posts, but there are other timezones with interesting people in them.
