> Global social networks are that megaphone.

Uh, what? No they aren't. If I shared something on FB or Instagram, it would be shared exactly to the people who I'm friends with on FB or follow me on Instagram. I, and I'm willing to bet really large amounts of money at favorable odds to you most other people, don't have anything close to 10K people in either of those categories. Weirdly, despite your favorable comparison, and in fairness to your point, Twitter is much closer to being that megaphone.

> This is why your feed, while having some gems, is also likely full of reposted memes, personality quizzes, and other retweeted/reposted content.

Actually it's almost entirely not this. It's mostly boring baby photos or engagement photos or posts about middling shit in most people's lives. I wouldn't be surprised if FB downranked that type of content a lot. On IG, it's literally none of that. Mostly baby photos and photos of little trips and outings people do.

> If you have no actual special connection to the person who is posting the meme/quiz/repost, it is just noise to you, no?

Why would I be connected to that person???

> there is a very good chance it’ll be a lot less interesting than a random post from e.g. Neil deGrasse Tyson or Neil Patrick Harris or Obama.

NDT: https://twitter.com/neiltyson/status/1371147864361996293 a meme joke about pi. So profound.

Did you know pizza is known as pizza pie and pie and pi are homonyms? Wow, thanks, Neil! Glad a leader in the field like you could hook me up with this interesting content that no average person could!

NDT: https://twitter.com/neiltyson/status/1371121692064374785 Normally, I would need a calculator for this content, but NDT has got my back on Twitter.

NDT: https://twitter.com/neiltyson/status/1370797127459278856 cute cows are cute, also pithy political statement. An average person might be able to post a cute animal OR make a pithy political statement, but BOTH!?

NDT: https://twitter.com/neiltyson/status/1369144426845663234 buy my merch! No average person could ever have merch! He produces great content like this on a weekly basis. Even if an average person was able to have merch, could they post about it weekly??

NDT: https://twitter.com/neiltyson/status/1366730477642649603 Faux deep statement with a picture of space. My grandma literally posts shit like this all the time, I'll let her know she's a leader in her field.

NDT: https://twitter.com/neiltyson/status/1366097324276027393 LOL dogs smell butts. Classic content no average person could do.

NDT:https://twitter.com/neiltyson/status/1365764623820029959 LOL DAE dogs shed on furniture!?

NDT: https://twitter.com/neiltyson/status/1363840108861005829 Same vacuous quips my teacher friends post when they're feeling down.

NDT: https://twitter.com/neiltyson/status/1363159290601758723 Seriously, it's all memey bull shit. I'm not even being selective here!!!

Let's do NPH.

NPH: https://twitter.com/ActuallyNPH/status/1364362084985823234 Thanks for saying nice things about me! Average people are never thankful for things in their lives!

NPH: https://twitter.com/ActuallyNPH/status/1355157217478123524 Just like MLM shit people post.

NPH: https://twitter.com/ActuallyNPH/status/1352751015121063937 Shameless self-promotion. Average people don't have personal brands that they self-promote. Just leaders in their field like NPH. This is the vast majority of what he posts. Thank GOD I can get this on Twitter by following leaders in their field instead of FB or Snapchat where people share stupid shit like their vacations with friends.

NPH: https://twitter.com/ActuallyNPH/status/1328787438232276993 Last one because I can't stand how ridiculous your lionization of these people is over the average person. Here he recommends a book, which of course average people, on account of being illiterate, could never recommend!
