I either select “All” or “Local” on occasion and don’t really pay attention to how those categories are filtered. The main challenge I see right now is that there is a lot of content not available or translated in English which leads me to blocking communities that otherwise have interesting and valuable discussion.
Plus there are challenges with figuring out how to find stuff that is new and insightful besides the regular defaults on the feed but perhaps part of that is simply because of not posting enough and being part of the experience.
