A data-driven post-mortem on Boulder’s election results.

A statistical model predicting city council races reveals a consistent pattern in how Boulder’s ballots are cast and counted — and why progressives keep coming from behind.

My first piece is on the consequences of a half-century of population anxiety and debunking myths about Boulder being "full".

If I could bind everyone to my idiosyncratic platform design preferences, I’d want an exponential back-off for active users’ post/boost time and what’s sent to followers.

Space out the posts from high-frequency users to leave some bandwidth in the reverse chron timeline for everyone else!
