there are a couple of things here
Firstly this forum is specifically for the LWJGL api, so people generally post questions and expect answers around this topic. This is the main reason why people would frequent here and because of the narrowness its the reason why the volume of posts is quite low. For java gaming related questions people generally post on
http://www.java-gaming.org/ and for opengl specific questions they post on
https://www.opengl.org/discussion_boards/. So try and understand the audience of where you are posting.
Like with all forums there are lots of helpful people around who can help out for questions wider than the remit of what those forums are really for and are always happy to help out, this forum is no different to them. But to get the maximum out of the people who do read these forums, you need to avoid the "here is my entire code, go figure out problem please" type questions. People don't have the time or motivation to do your work for you! As Kai has already said on the other thread, a small repeatable example is always the best way to demonstrate a problem and is likely to get more of a response.
And finally, don't take it for granted you will always get an answer!
