I found the extra flexibility really useful. I could have an arbitrary number of words or hashtags in each antenna, rather than 4 like mastodon, which allowed me to cover all of the variations I wanted. I could use multiple words on one line for a boolean “and” function. Rare words, I would use without hashtags, common words, I would restrict to hashtags.

I could follow instances, I could follow people, I could follow keywords, and I could follow regular words, with more control than basic hashtags.
