That's a little unfair. COBOL just isn't well suited to problems solved by a new web framework. Batch processing of financial data is important, but it ain't likely to generate buzz.
Point taken, but Perl has a (very) long history of being the glue the holds websites (and everything else) together. I think perl files in cgi-bin is the first time I ever connected a database to a web page.
COBOL has an even longer history processing business and financial data. Perhaps COBOL is the secret sauce that hedge funds use for high frequency trading?
