   Marco Rubio was my senator. He and his staff politely listened to me, and their support was vital in getting hammerhead sharks protected in Florida waters.
   
   I was cautiously optimistic that he might maybe be a voice of reason.
   
   Yesterday shattered that.

   This seems like a great day to remind Bluesky that Stephen Miller lived four doors down from me freshman year
   
   And our student council person asked him (and everyone) to sign a birthday card for our dorm’s janitor
   
   And he threw a tantrum and wrote an op-ed about not socializing with “the help.”

   Bright passionate people who wanted to dedicate their lives to public service were fired in a mass email over the holiday weekend.
   
   This has absolutely nothing to do with efficiency, fraud, waste, or abuse. And your life will be worse because of it.

   I don’t use social media to argue about politics with strangers.
   
   I use social media to talk to people about fish.
   
   When I talk about fish on Bluesky, people ask me questions about fish.
   
   When I talk about fish on Twitter, people threaten to murder my family because we’re Jewish.

   "Bluesky is an echo chamber." "Bluesky doesn't have enough reach" "Liberals must return to X to challenge the far right" I'm not a tech bro or a journalist. Your priorities are not my priorities. Stop telling me I need to do anything other than chat about comics & telly with people who seem nice.

    Hey everybody! @drjuliawester.bsky.social and I have a new paper!
    
    We surveyed over 800 scientists, science communicators, and science educators who use social media.
    
    Conclusion: Scientists no longer find Twitter useful or pleasant, and many have switched to Bluesky! 🧪🌎🦑

    One of my dissertation chapters had a tentative working title of “did the internet create annoying people, or just make it easier for existing annoying people to find and annoy me?”
    
    The answer is yes.

    In honor of Mr. Rogers’ birthday, here’s your regularly scheduled reminder that the quote of his you keep sharing, that in times of crisis we should look for the helpers, was for his audience of children.
    
    We’re adults now. We’re supposed to *be* the helpers.

    I saw someone post, apparently seriously, “we don’t need NOAA, we can just ask ChatGPT to predict where and when hurricanes will hit.”
    
    I don’t think we should sentence thousands of people to death because some overconfident buffoons don’t understand how science works.

    Since we’re in a golden age of new Star Wars tv shows, I’ll again pitch “David Attenborough style nature documentaries but of fictional Star Wars creatures.”
    
    No empire. No Jedi. Like, what the Jedi would watch on tv to relax after a stressful mission.

    If you find that your uninformed personal opinion disagrees with expert consensus on a technical topic, please consider that “all the experts know something I don’t” is a much more likely explanation than “I alone solved a complex problem that all the world’s experts have long been studying.”

    Bottom trawling, dragging a heavy net across the seafloor, has been compared to burning down a forest to catch rabbits.

    Great white sharks can jump higher than the average house. This is because of powerful muscles, a sleek fusiform shape, and the fact that most houses cannot jump.

    One way that you can tell a shark scientist from a non-expert enthusiast in online discussions is that the non-expert enthusiasts will say things like "Look at that Galeocerdo cuvier! " and professional shark scientists will say "that stripey boi is chonky!"

    Eileen and I do pub trivia each week with friends.
    
    Last night I arranged for the last round to be “wedding and proposal traditions from around the world.”
    
    On the last question, the hosts said “I need help with this one, David can you come up here and ask it?”
    
    She said yes! We’re engaged!
