Del.icio.us + Google Custom Search = Delizzy

In my April 9, 2008 blog post on "Social Tagging and Vertical Search" I had talked about exactly this idea:

For quite some time now I wanted to build a mashup using the social tagging information from del.icio.us and combine it with Google's Custom Search engine. This is a neat way to build high quality vertical search engines. (For example we could use all the URLs under the tag "astronomy" to build an astronomy vertical).

Well, it was just waiting to happen. Delizzy (via Techcrunch), is a wonderfully simple idea but it is a super cool site built using del.icio.us and Google Custom Search. It lets you do what del.ico.us has surprisingly, still not yet provided -- A full text search over your bookmarked items. I believe this could be taken a step further and built into custom search engines or verticals for different topics. Imagine searching over only highly bookmarked sites for a particular topic like "AJAX" or "Ruby on Rails" or "Artificial Intelligence".

In any case Delizzy is pretty cool. Go check it out!
