Daymix looks like a nifty web application. You type in a query of something you’re interested in and it returns results from delicious, twitter, Google, Google Blog Search, Flickr, and Twitter. I’m adding it to Not “The Best,” But “A List” Of Search Engines For Social Media, but that’s not really why I think it’s “nifty.”
The particularly nifty aspect of it is that you can get an embed code for a widget that you can place on your blog and website that is supposed to continually update results from that search query. I’ve embedded a widget with the query “ESL + EFL” in this post, but it probably won’t show-up in an RSS Reader — you’ll need to go directly to the blog to see it.
