A quick check of indeed shows one job with Delphi as a nice to have within 100 miles of San Jose. For python, 11000. Ruby, 559.
"Delphi programming" on google, the string that the delphi has been trying to push, gets 127,000 hits on google, "python programming" gets 17,100,000
In computer science, Amazon shows 600 delphi books, with the top book having a sales rank (lower is better) of 1,600,000. Python, too many to count (says over 10000) top sales rank 1000. Ruby, just below Delphi in Tiobe, over 10000, sales rank 800,000
So, basically: no google hits, no book sales and no jobs. How is that number 16?
