I've answered a number of questions on Stack Overflow recently where it is obvious that the poster has just blatantly used Stack Overflow as a substitute for loading up their own IDE/language documentation or helpfile.
There have been other questions I've answered where it took me a 30 second Google search to find the relevant information.
It probably took the poster longer to enter the question in Stack Overflow than if they had bothered to make the small amount of effort to look it up for themselves, but I guess they were off getting a coffee or having a chat and decided to offload the effort "virtually" onto someone else.
Sure, answering these questions gets you a bit of reputation points in return, but it feels like a hollow victory, and it leaves you feeling a bit "used".
It's as though Stack Overflow is encouraging a habit of laziness amongst a certain class of developers, and this attitude may well spread as Stack Overflow becomes more popular.
Is this a concern that should be addressed in some way?
I know you can downvote questions that are obviously silly, but unless you have a decent amount of reputation points built up, it feels painful to do so.
