Sorry to drag the discussion back to figures...
I think that many questions and answers would be assisted by the inclusion of an appropriate figure or two. A rendering of the latex or a screen capture from a different program or whatever. However, in the rush to provide a fast answer, I think that people often skip the several steps required (write a file, compile it, view it, screen grab, save relevant part to disk, upload with the excellent no-so-new button), due to the time/effort it takes, or because they are unfamiliar or uncomfortable with part of the process (heck, I myself sometime can't be bothered).
I think that it is a problem and I would like to solicit feed back on two questions:
What do you think? is it a problem? Should we somehow promote the inclusion of figures in answer and questions?
if you think that the answer is yes, perhaps you can also answer the second question:
How can we do it?
I have some ideas, but I will first open the floor to others.
