[plt-scheme] blogging software in Scheme?

For the course blog for my HtDP-based first-year course, I've been using 
Blosxom 2, a small, modular Perl-based program. Development of version 3 
seems to have stalled, and it would be nice if I could use Scheme for 
blogging (as I do for generating other course materials, including 
slides, course notes, and Web pages). So I'm asking if anyone has 
anything to share in this respect. (Or, if you don't, but you like your 
blogging software, please drop me a private note to tell me why I should 
switch to it.) Thanks. --PR
