unless you are known nobody talks
Not really, we all start as unknowns
waste of time and space
Some truth in that, however this forum is great specifically because most questions here get useful responses or none at all. There is in my opinion a tendancy towards only answering questions where it is possible to diagnose and suggest fixes for the problem that will work more often than not. And yes it means that not all questions gets a response within a short space of time, but in my opinion bettter than someone suggeting you do a disk defrag and reboot irrespective of your problem, as a result a lot less waste of time and space than the alternative.
