If you haven’t seen this yet, it is sooo cool. Micah Alpern has put together a script that lets you do a search of only those sites whose RSS feed your subscribe to using the Google search API. It uses your mysubscriptions.opml file, which contains all of the RSS feeds that you subscribe to, to set the scope of the sites to search. And in a brillant turn of usability, he added one’s own blog and the web in general as the other two ‘collections’ to search through the same search box. Plus he’s built a little form on his site that will generate all the code for you. All you need to do is go get a free account at google in order to get an API key, and away you go.
You can try it out on the right hand menu. This is great both as a personal knowledge tool, but also to allow you to look deeper through other people’s prisms on the world. – SWL
