Interested in knowing if vibrant online communities exist where people talk shop similar to HN for other industries, e.g. construction workers, teachers, actuaries, doctors, etc.

For frequent flyers, FlyerTalk is excellent.<p>It could also be described as the birthplace of WhatsApp, in which one of the co-founders asked for 'thoughts on my free iphone app'[0], which is amusing in retrospect.<p>[<a href="https://www.flyertalk.com/forum/travel-technology/952359-thoughts-about-my-free-iphone-app-whatsapp.html" rel="nofollow">https://www.flyertalk.com/forum/travel-technology/952359-tho...</a>]
Any number of subreddits?<p>Construction workers - <a href="https://www.reddit.com/r/Construction/" rel="nofollow">https://www.reddit.com/r/Construction/</a> "A subreddit for construction industry professionals."<p>Teachers - <a href="https://www.reddit.com/r/Teachers/" rel="nofollow">https://www.reddit.com/r/Teachers/</a> "The goal of r/Teachers is to provide a supportive community for teachers and to inform and engage in discourse with educational stakeholders about the teaching profession."<p>Actuaries - <a href="https://www.reddit.com/r/actuary/" rel="nofollow">https://www.reddit.com/r/actuary/</a> "Articles and links of interest to those in the actuarial profession."<p>Doctors - <a href="https://www.reddit.com/r/doctors/" rel="nofollow">https://www.reddit.com/r/doctors/</a> "This is a community for clinicians."<p>Etc.
Slashdot is fun if you want a more cynical take on some of the topics that show up here. Slashdot's articles typically are general tech, science, security, and politics (esp tech related). Here there's more software community stuff, blogs, update notes, personal projects etc. I read both HN and slashdot daily, they each have their own thing.
I continue to be impressed with the lesswrong "site" which, it seems to me, is the proper evolutionary step forward from a BBS onto the medium of the web.
<a href="https://www.reddit.com/r/machinelearning" rel="nofollow">https://www.reddit.com/r/machinelearning</a><p>Very high quality.
Arfcom GD: <a href="https://www.ar15.com/forums/general/General-Discussion/5/" rel="nofollow">https://www.ar15.com/forums/general/General-Discussion/5/</a><p>Definitely a right-wing slant, but there are ton of very knowledgeable people there. Signal/noise ratio is kinda middle of the road, but the quality of the signal more than makes up for it in my opinion.
Aviationherald, it's a bit of a mix but there are some really knowledgeable people on there.<p>also: <a href="https://theairlinepilots.com/" rel="nofollow">https://theairlinepilots.com/</a>
BiggerPockets.com is great for real estate (but beware of the scammers).<p>bogleheads is great if you're into personal finance of all sorts<p>airliners.net is great if you're into airline operations; PPRuNe.org too
For the same industry:<p>- <a href="http://indiehackers.com" rel="nofollow">http://indiehackers.com</a><p>- <a href="http://getlatka.com" rel="nofollow">http://getlatka.com</a>
I don't think there's anything comparable in terms of activity/traffic. Lobste.rs is the closest but it just has way less active users and daily content.
