GreenOptions.com, an online destination for 'green living', including a constantly-updated blog featuring some of the green blogosphere's best writers, a green living wiki with a wide range of practical information, a central news page for green stories from around the globe, discussion forums to share your own green practices and insights, and tools to help you make the jump to solar energy (and eventually other technologies) for your home or business.
The basic idea is for people with ideas to come together to splice and build on them together then to use Drupal tools to make them happen. The key thing is no one's in charge, no right or wrong ways of using the site...just giving people free reign to do whatever they want.
I am very impressed at how quickly I could get a site up and running without weeks of digging into documentation and many 'false starts'. I had a Joomla site which just wasn't working out because of the learning curve, lack of nice variable width 'open source' themes and I couldn't figure out how to do sub-menus (wow easy with Drupal). Had been looking at possible options and after seeing the V5.0 announcement (Joomla site) I decided to take a look.
I don't want to bag Joomla as it has some very cool stuff. It just didn't fit here.
I started the blogging thing with WordPress a few months ago and was pleased, but it turned out to be very limited. I started playing with Drupal and loved it. I switched the my site http://www.livingwithmac.com to drupal this week. The idea for the site is to provide videos on my experiences of living with a Macintosh, video overviews of applications, as well as news items I find interesting.
