I'm a take off work to watch the entire first weekend of the NCAA tournament kind of guy. I don't understand expanding the tourney to 76 teams. I have no desire to watch 9-11 Minnesota play play 8-12 Auburn days before 65% of their players hit the portal.

My original conspiracy theory is that auto companies manufactured @oliviarodrigo and her big song "Driver's License" because of concerns about declining Gen Z interest in driving. Olivia, welcome to the @waroncars.

Today marks 7 years since our last traffic fatality in Hoboken, 1 of the only US cities to reach this milestone. Although we’ve had success creating safer streets, we’ll continue to aggressively implement Vision Zero in all major infrastructure projects. jalopnik.com/traffic-fatalit…

Everyone loves to hate on corporate landlords. Today, I'm going to show some love. Corporate landlords shovel their dang sidewalks! In DC and Philly, it appears that approximately no one else does. Thank you, corporate landlords, for doing your part.

The most striking thing about my walk this morning was condo buildings with 100+ units that had not shoveled their sidewalks.

Holy buried lede, batman! Norway, Finland, and Denmark, where college is FREE, have pretty similar student debt to the U.S. xitter.cf/jburnmurdoch/status/17…

Oh, and a bonus chart that I think will fry a lot of people’s brains and break a lot of narratives: For all the talk of six figure costs of college in the States, here’s how much debt graduates leave university with in the UK and US vs other countries

Yesterday I saw a guy driving a massive pickup truck after dark while texting and smoking cannabis.

BREAKING: The IRS is using funds from Biden's #IRA legislation to launch a free online tax filing service, Direct File, in 2024 for taxpayers. The program will be piloted in 13 states, saving working families money, time, and stress. This is progress. cnn.com/2023/10/17/politics/…

Warning: the visual editor in @posit_pbc's RStudio will reformat your README.md so it no longer correctly renders on GitHub. I only touch the visual editor for the Zotero integration. Otherwise it's just pain.

My most deeply held belief is that Olivia Rodrigo is a conspiracy by the Big 3 auto companies to get youths who stopped caring about driving and licenses to care about driving and licenses. youtube.com/shorts/jmWhFGGwK…
