Most underrated Reddit subs?
I like r/games a lot. It takes all the problems with r/gaming and fixes them.
Such an interesting idea for a subreddit. Everyone has seen many buildings like this in their home town no doubt. It used to be a very active sub but died quietly about 2 years ago.
AskHistorians is excellent and very informative
syriancivilwar is an amazing place to keep up with events in Syria, constant stream of updates and some very informative posts now and then
YemeniCrisis and LibyanCrisis are the less active equivalents for their respective wars
AskScience is great but too broad for me since it covers questions about every field
