I seem to see this type of attitude regularly when talking about digitizing. There are obvious techniques that some digitizers use that could be helpful to those learning, not tweaking of parameters but things like "double the density", "start from a corner", etc.. A "go figure it out yourself" type response doesn't help anyone. I understand that tweaking and re-sewing things helps the digitizer learn and see what the changes actually did but discussing how to approach something or general concepts greatly helps others. In my field the sharing of information, approaches and techniques is welcomed and creates a strong support/learning system for all parties, including those that like to tell others to figure it out themselves (they did or will sometime need help also). After all the internet is about the sharing of information
