It is primarily a playground for me to try out things with Drupal. Recently I've started using it as an RSS aggregator to take the place of Google Reader.
Bummer. I've been using google reader for several years. I'll probably use the Drupal aggregator module to reproduce the functionality but I'm still a little disappointed.
So I didn't really care for the webDAV module for Drupal 6, but it turns out that my hosting company (dreamhost) had a pretty nice and easy to use set up to run webDAV directly from their webserver. Nice of them.
I'm hoping that by installing the WebDAV module for Drupal here it will give me a free Dropbox style way to sync things between my idevices and my computers. We'll see.
