Once the userbase gets to a certain size, I imagine a truly unfiltered global feed will be unfeasible.
By unfeasible, I mean it would melt the phone/laptop/router of the average person. Imagine if a social network the size of Twitter had a global feed?
I do think we should leave it as an option for those who want to drudge through it, but it seems like going forward, a "discover" tab will probably make sense to replace it.
To be clear, I'm not advocating for an algorithmic one, more like a leader board of the most liked/boosted posts of the day or something.
