I dissagree. I don't believe familiarity with anything other than Perl (or even Perl itself in our newbies) is really assumed. I think that statistic about 90% of our content being CGI related is rediculous. Probably less than half of our Monks could use the Document Object Model competently. That's an offhand guess though, as everyone is free to define 'competent' as they please. ;-)
Conversely, if the monestary were to accumulate one new section at a time, it would certainly pick up HTML before Basic. I imagine a potential order might be: Databases, Security, HTML, Python, Java, C/C++, etc... but really, who's to say?
