A few months back we created the first ever website for the Metronauts; a community initiative here in Toronto that seeks to encourage conversation about transit in and around the GTA. This initial website was built in Drupal and featured a few cool tools like a content voting system that automatically gave site users 'karma' for posting comments etc...
After some time online we all decided that first and foremost, our aim with the site was to get people talking - and showcase regular contributers whilst bringing the general public into the fold. So, we moved the old site into an archive and got a few people together to whip up a Wordpress blog - complete with custom theming, social tools integration and email newsletters - powered by both Feedburner (for auto-mailing of new site content) plus our own ajaxy Design Guru email service (more on that soon).
