curating the right follows on Twitter (FinTwit) is the closest thing you will find. You could follow people like @CliffordAsness (a well known and outspoken quant) and just choose some of his follows. The toughest part is disentangling the good accounts from the promoters. valueinvestorsclub.com is great. If you get Bloomberg, there are industry/interest specific anonymous chats that are useful as well.
