Yeah, I'd been sorta looking into
Template-Toolkit, too. Seems like that it would be a better fit if you want to read in an HTML template and fill in certain values. My thought is that if you use that, then people maintaining a website using Template-Toolkit wouldn't need to know the CGI.pm syntax or even perl; they would pretty much just have to know perl, and with so many HTML GUI editors like Dreamweaver, BBedit and Microslosh Word, this could make sense. That way, you can hand off more of the mundane day-to-day stuff to someone else, and spend your time reading slashdot or perlmonks. :)
I've also heard a lot about HTML::Mason as well. That's if you have a large site to manage. I saw a job posting for ebay a while ago, and here are some other sites that use it. I think there are some Oreilly books on them, too.
