Twitter is very good for this, but you must follow the builders. Wholly agreed, there is too much trash if you just search for crypto. I'd recommend finding the founders and devs of a crypto organization or protocol you find interesting and follow along.

Some high signal ones are @Bantg from Yearn Finance, @gakonst from Paradigm, @epolynya for Modular Blockchain info, @iamDCinvestor for macro view and NFTs.

You can find a lot more good ones by seeing these individuals replies. And if you like, you can follow me as well @_nd_go, I try to keep my feed fairly high signal
