I have a column in @boulderreportinglab@toot.bldrweb.org about the implications of the "tipped wage offset" and its implications for deteriorating housing affordability in #boulder https://boulderreportinglab.org/2026/05/10/brian-keegan-boulders-tipped-wage-debate-rests-on-a-myth-about-what-restaurant-workers-earn/
“When antidemocratic politics target universities, universities need more democracy, not less, to protect themselves. Recognize the collective bargaining rights of Colorado’s public university employees.”

I'm teaching a five-week mini-course on Web Data Scraping. Twitter was ejected from the course but we'll be digging into the Mastodon API.

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.
“We need more safe, walkable, mixed-use spaces throughout #Boulder where residents and visitors alike want to linger, shop and dine — not noisy and car-choked corridors that prioritize parking over placemaking.”

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!
My latest Charting Boulder column in @boulderreportinglab@toot.bldrweb.org "That’s the promise of public interest data science: not just to mythbust, but to make arguments about our community more accountable and actionable." https://boulderreportinglab.org/2025/07/22/brian-keegan-rethinking-boulders-growth-debate-with-data-not-nostalgia/

Thank you to @boulderreportinglab@toot.bldrweb.org for bringing me on as a regular columnist.
My first piece is on the consequences of a half-century of population anxiety and debunking myths about Boulder being "full".
Awesome new paper from @sohw, @healspersecond, @aaronshaw@social.coop

Despite its attractiveness, the particulars of joining Mastodon and discovering relevant people and content was difficult for a large portion of our respondents.
Finally, we report widespread differences in perception of both Twitter and Mastodon, with Mastodon being seen as safer, better for protecting privacy, and more in line with personal values, even among respondents that currently use Twitter more than Mastodon. (3/N)
A new column from yours truly on the changing demographics of #Boulder and its implications. https://boulderreportinglab.org/2025/08/26/brian-keegan-how-boulders-silver-wave-could-transform-the-citys-future-for-the-better-if-we-plan-now/
I won’t be at #CHI2023 but be sure to keep an eye out for @samanthadalal@hci.social presenting her paper with @YuhanLiu@hci.social and @andresmh@hci.social on indie food delivery platforms! https://dl.acm.org/doi/10.1145/3544548.3581517

While our sample may be skewed towards those who felt strongly about changes to Twitter, these results imply that the migration from Twitter to Mastodon was driven less by re-building one’s social graph and instead was governed by other “push” factors.
This could be evidence that the network effect-driven “growth hacking” strategies that dominated venture capital-backed platforms through the 2010s may be bumping up against users’ concerns about usability and safety. (4/N)
“McCartney used his CU position and the evangelical men’s rights group he founded to publicly repeat his homophobic and patriarchal views for years. Nobody should be forced to see a monument to this man.”

@drewww I polled the early-summer members of hci.social about this if you can get to the beginning of my timeline.
tl;ds: Most people were ok with talking about personal/off-topic stuff, maybe use content warnings/subjects. I have been for months and haven’t received negative feedback.
