Lots of people have contacted me, asking for a version of my Flickr widget that they could use on their website, without having to use Flickr (or Picasa). Doing such a version was easy enough, but I was hesitant to release it. The DIY version of WP-Cumulus has yielded more support requests than the actual WordPress plugin, and answering all the email has been taking a lot of my time.
One thing I could have done was to simply release the sources for the Flickr widget. But there’s a lot of Flickr/Picasa specific stuff in there that you would need to take out before being able to hook the movie up to another data source. So that would have made things harder for everyone.
