I've seen the same thing and it's reassuring lol.
I lurk on subreddit drama and curated tumblr, and I feel like the common reaction to LW has gone from a few negative comments and "really? that's crazy"'s five years ago to being much more aware. Years ago you'd see maybe one person familiar with them and then a couple people respond who are totally out of the loop and maybe you'd see one crazy rationalist chime in to nuh-uh them. Now, anything rationalist-related usually has a bunch of people bringing up the harry potter or acausal robot god stuff right away.
I use the tag feature a lot in RES to keep track of people who I like hearing what they have to say. Years ago I mostly saw the same names when LW stuff came up, but now there's always a ton of people I've never seen before who are familiar with it.
It's also reassuring because I really don't want to be the person to say anything first and it's easier to chime in on a discussion someone else has already started.
Fortunately the EA side is a little more on the nose sometimes.
One of my first wakeup calls was they offered to mail me a book for free🚩🚩🚩 (it was from 80,000 hours)
