The speaker says he has repeatedly found that people whose Twitter posts seem funny and insightful appear unintelligent when met in person.

“I will mention something that has actually radicalized me against Twitter as an information source is I'll meet,”

“and this has happened multiple times,”

“I'll meet somebody who seems to be an interesting poster,”

“has,”

“you know, funny, seemingly insightful posts on Twitter.”

“I'll meet them in person.”

“and they are just absolute idiots like there's like nothing it's like they've got 240 characters of something that sounds insightful and it matches to somebody who had maybe has a deep world you might say but they actually don't have it whereas i've actually had the opposite”
