FlickrInspector takes a Flick username, userid or email as input and returns more information than I would have thought possible. It displayed profile information, most recent photos, oldest photos, most interesting photos, tag cloud with some statistics, sets and searches for blogged photos.
Preloader allows you to edit your Flickr photos completely online with no additional software installed on your computer. It allows you to tweak brightness, contrast, hue, etc. along with rotation, flip, crop, and many others. I’m terrible with photo editing software, so here are a couple of screenshots from other blogs.
The beauty in this is not that there are two more tools that work with Flickr (even though these are two pretty cool ones!) The beauty is that web 2.0 applications, like Flickr and many, many others, are architected to make it easy for people to write new applications using the information and value in Flickr in a slightly different way. For example, FlickrInspector was written by Nils K. Windisch aka netomer from Germany in his spare time to improve the user experience of Flickr in a way that made sense to him, and after writing it, he shared it with the world to enhance the user experience of others. Flickr is a great example of the Architecture of Participation in use and harnessing the collective intelligence of your user base.
