There are lots of helpful posts on this subreddit.  I'd argue, between the shenanigans and tom foolery, this sub has the most solid trading/investing advice  of all similar subreddits.

Totally agree. You have to sort through a ton of shitty advice to get to that good advice, sure, but it's definitely there, and it's easily better than any of the other subs regarding trading.
