&gt; I&#x27;m really surprised that software developers aren&#x27;t more the sort to really say &quot;why am I doing this?&quot; and to prefer systems which make it easier to answer those questions with pretty pictures.<p>The network effect should explain it.<p>That said, using pictures to answer questions is fairly sadistic when those asking them are blind. I know a blind developer and I never use pictures when talking to him in IRC.
