I just saw that well written comment and was thinking it's a crazy thing - that an astronomer at a large gathering of astronomers, surrounded by so many interesting people, discussing so many interesting things, takes a timeout to go and post an elaborate comment on reddit.

What is that crazy need we have to put in work, for no great gain, to keep utterly random people around the world updated in real time of whatever is going on?

These days, I seem to stop myself reading the news article , just head over to the right forum, and look for such comments. It's like the news industry has become more or less irrelevant, other than in surfacing a list of headlines, which then seed my "find best comment" search algorithm.

Not such a crazy thing at all! From an astronomer's perspective, it's a rare opportunity to connect to people not working in the field about his/her field of study. Trying to break down all the jargon and explain the general state of the field is a mental exercise akin to cleaning your desk - it's both satisfying and puts things in place.

We don't get a lot of opportunities to talk about this - you can't annoy your friends with work talk all the time, so going for "utterly random people" is your only chance unless you're in science communication.

Funny that your meta comment is not an example of 'such comments' and is 'more or less irrelevant'

Going completely off the rails is the norm for reddit and I would never use it as a reference for anything.

You can however find subject matter experts that can point you in the right direction. Maybe.

Don't trust, and verify.
