I think this place is too fragmented into instances to ever generate a front page anywhere near what r/all is.
If I understand this page right, https://lemm.ee will never show the top post of the day from https://lemmy.blahaj.zone/, https://discuss.tchncs.de/, or https://feddit.uk/.
And the “front page/general” site is already split into several instances (https://vlemmy.net/, https://lemmy.world/, https://sh.itjust.works/, https://lemmy.fmhy.ml/ and https://lemmy.one/, all claiming to be “a general front page lemmy instance”)
So what’s the deal, which one are we betting on as the place to direct all the new traffic? What’s the contender for primary public internet bulletin board? Right now the arrow to an alternative is looking like this: https://i.imgur.com/L1XsBy6.pngd
I’m personally guessing the conclusion is already reached; We have no place we’re betting on. We’re disinterested in pushing for any particular result. We don’t expect people to migrate. Many might not even want them to.
To be honest, effectively that’s the result anyway, as I believe most communities that get very popular posts already have at least 1 subscriber on lemm.ee, and there’s no reason to expect this trend to ever change.
