This is true, but: for many areas of expertise where I am pretty much ignorant, I wouldn't even know about existence of certain terms, ideas and starting points if I haven't first read about them on internet forums. With the obvious disclaimer that I usually do a followup readup on such topics. So "stop reading these and ask an expert" is obviously a good piece of advice for someone seeking resolution of their own serious problems but there's still value in reading internet discussions.
