Ever since I discovered Technorati Tag Searches
I've been doing them as one of my first steps in searching on any subject. Technorati searches tagged blog posts, flickr shared photos by tags, furl and declicious bookmarks. I have been very impressed, until I discovered Tag Central
, a scrappy little outfit put together quite well, apparently just using RSS feeds from Technorati, Flickr, Furl, Delicious and 10 other tag-enabled search engines. You can also grab the RSS feed URL for your search in each engine as well, and receive notification of new results in your feed reader as they become available.
It almost seems an experiment, it's so simple, but I expect it will be useful. It's a great example of what kinds of things the world of web applications can do and should be able to do more of in the future. As with all folksonomic endeavors (popular classification), the value of the data set will depend on its number and diversity of users.
