Like any advice some is good and some is bad and one has to filter as best they can. I don't see any reason one can't interact with smart guys like William the Wie and get some useful solid info or at the very least have a discussion where they can bounce their ideas off each other and maybe gain some new perspectives. I've seen some outstanding threads on bogleheads, morningstar, and early retirement forums where people have questions and get great answers.
Conversely many an investor has gone to a "professional" and ended up with a financial adviser who loads them up with funds they get a commission on and take a fee on top of it, or bought a book by an "expert" that had them making all sorts of poor investment decisions based on expert's opinion of what will happen in the future regarding inflation etc.
Good advice = ask away, but keep a gain of salt handy.
