something as simple as a JSON-aware guestbook backend for an AJAX website

I've been programming for a few decades, and Perling for 6 years, and that sentence means almost nothing to me. I'm vaguely aware that AJAX is roughly the web equivalent of "raw mode" for http, but I've not the vaguest clue what JSON is. And I've never wanted to write a guestbook. (Nor contribute to one!)

And I'll never understand the need of Perlers to want everyone else to use Perl?

I love my 20 year old Japanese sports car. It is economic to run, 40mpg when driven with a modicom of care, low service costs and barely a sign of rust after 20 years of non-garaged daily use. And yet has enough performance and handling to provide a few thrills on those rare occasions I get to take somewhere I can utilise it safely. But I never felt the need to encourage all my freinds to get one, never mind strangers. Indeed, part of the original reasoning for buying it was the small degree of exclusivity it provided.

If other people are happier to use $Otherlanguage, why does that bother you?
