So here I am, new to bitcointalk today what and what benefits can a newbie gets from spending their time on this forum?
The "benefits" you can get off this forum is the exact same "benefit" you can get by joining various forums/communities concerning whatever topic — you get to talk to other people about that certain topic.
Probably not. The resources found in this forum is incomparable to the resources found in other forums, definitely more than all of theirs combined. History happened here. The baby steps of Bitcoin took place here. Discussions as to the official Bitcoin logo, number of decimals, and many others happened here. If OP is interested to read more about the past, this forum can offer a lot, discussions that are so rich, discussions in which Satoshi himself participated.
But as far as current discussions are concerned, I agree with you.
