As an analogy, I go to r/spacex, see important things that are being mentioned, and post it in [email protected] with a link to the original tweets or articles or whatever. Wikipedia may say

the name “Reddit” is a play-on-words with the phrase “read it”, i.e., “I read it on Reddit.”

but for a good number of posts, you could describe them as “I read it somewhere and decided to post it here”.
