Whenever I go on Stack Overflow I'm always afraid that my questions won't get answered the way I want them to be. I won't get the right answer to one of my questions.
This often demotivates me from even posting a question. I found that I often wasn't able to get across exactly what I wanted to do, and if I did, I often didn't understand the answers that people gave me.
What I'm trying to say is that there's a communication problem between question and answer boards.
What if we had the option for people asking questions to show that they were online and on something like Skype? Then if someone thought they knew the answer, they could try to answer it with Skype? The immediacy of responses would decrease confusion and people could solve problems more effectively, and perhaps even more efficiently. People could even show screen actions in real time with screen recording software instead of a webcam.
