was literally just thinking about this yesterday, definitely want to do this. it would be really cool if you could make not just pinned hashtags but hashtag groups.
#tag1#tag2 and #tag3 could all show up in a “feed” of hashtags.
I definitely think the mechanism should allow for "pseudofeeds" that merge multiple hashtags, if not getting into more elaborate logical-operator combinations (which, as @mozzius.dev noted, starts to get into feed-generator territory)
@pfrazee.com probably has some ideas on how/if the latter could be implemented. but i'd at least right now like to be able to sort them by recent (current) or top (same way Twitter's search for a hashtag works)
