Anything that is not bitcoin related needs the #grownostr tag. I gained several followers posting about my #homestead by using that tag. Secondly, I see lots of notes show up with #permies. Since a lot of permaculture enthusiasts are homesteaders and vice versa you can gain attention by taking advantage of the crossover. Finally #farming and #farmlife seem to be popular among people that would be interested in #homestead.

I came to the conclusion above by searching different #’s, scroll down a bit and see how many posts contain that # for a certain time period (whatever sample size you want.) and divide by the number of posts to get a rough estimate of popularity. Read a few posts to make a judgement on relevance and make sure you aren’t spamming.
