@stux #socialdiscovery has suffered a bit although and requires the #extensive use of #hashtags to help spread the #word and have the same #reach.
This is possibly problematic because #hashtags aren't moderated at all, allowing other parties to infiltrate and overwhelm feeds by spamming irrelevant posts with a specific hashtag.
"That's the #freespeech," some would say. Well, others say it degrades the quality of your #timeline. Some would reply that you should just follow the people that you want and associate with #instances and #federations that you are interested in.
It is a difficult thing, and the idea of #groups as some has proposed might be a good idea. Because I myself don't see anything relevant in the #hashtags in the #mastodon app. Where an algorithm could help a bit, but then again, that information needs to be extracted from somewhere, again coming down to #privacy and #moderation.
I would like to see a page of hashtags people I follow are following.
