I have always rather regretted the “This forum is not a helpdesk” line in the How to help us help you post. It seems a little brusque, particularly towards people who lack the technical and/or language skills to explain a problem clearly. And, of course, there isn’t a helpdesk.
On the other hand, I haven’t seen the “Read the docs” jibe for some time.
And it can be very, very annoying when people plough on, blaming the integration/latest update/UI/protocol, without reading the answers and explanations they’ve been offered (and certainly not clicking on any of the links). You know who you are… 
On the whole, though, I find using the forum a positive experience. If a little addictive.
