we could add this to seedit https://plausible.io it lets you show public stats, could be interesting https://plausible.io/eth.sucks

seems more private than google analytics, it's open source, and it shows the stats publicly, so it seems like aligned with the plebbit ideas.

im not sure it makes sense to not have any tracking since plebbit makes tons of external requests, to github, to ENS/SNS, to every image it embeds, etc.
