The web is a HUGE place and yes , just about anything you can ask can he answered with a web search but often not without wading through tons and tons of bullshit.
Same goes for this site.
Nearly every question you see here has been asked at least once and some point or another in the last 18-19 years but again the search can be deep and the exact answer you are looking for might not be answered.
Not everyone has hours a day that they can be on the web looking up shit so I totally understand when someone ask a question that seems like it should be an easy answer.
There are alot more good helpful people on this site than assholes and I get the frustration when someone sees something asked for the 27th time but it really doesn't take any more effort to reply with a helpful comment than it does with a sarcastic one.
Don't ever hesitate to ask questions , you will inevitably get a couple useless remarks but don't let a few bad apples spoil the barrel , there is alot of great guys in here with a tremendous amount of knowledge.
