Developer survey...

Developer survey...  Doug S. (friend, former colleague, and Idaho mogul-of-everything) sent me a pointer to an interesting survey by StackOverflow.  It's full of interesting tidbits.  The one shown at right was the biggest surprise for me: 42% of all developers responding said they were self-taught!  I've known quite a few developer who were, like myself, self-taught – but it's certainly not two fifths of them.  It's probably more like a tenth.  This makes me wonder what's going on here.  Is my personal experience at odds with norms?  Or is the StackOverflow site more used by self-educated developers?

Something I found amusing: the most dreaded language or technology was Salesforce.com...
