On hashtags.
They make the Fedi what it is. They are respectful and anarchic.
A post on US politics? My friends who can't process this any more: they can filter it out if I flag it with a hashtag.
I write about an obscure poet? Those who are curious but unaware : they will find my post if I flag it right.
A long-standing line of posts on my dog? I give it a unique hashtag and others can follow up, if they so wish.
Most importantly: we don't sell. We don't maximise finds. Let the world find your post when the world is ready for it. Never make an exhaustive list of hashtags that cover all aspects. 2-4, maximum 6.
Your post with its hashtags is a letter in a bottle, floating in the ocean.
It need not be found. Randomness is good.
Make your hashtags partial. Make them obscure.
The Lady Joan Mastodon once told me: Roamer, use hashtags, they are what will make us win. But use them wisely. Confuse the Great Algo. Trust in chance.
