Sleepiness in Seattle

Custom search another interesting tool from Google.  Comparing with live search macro and yahoo pipes, I think allowing public contribution of adding good sites to cover and a handy "marker" tool is a big plus.  This helps take advantage of the community.  But some more powerful operators (like those on live search macro and yahoo pipes) are missing.  Another idea I have is to provide integration with bookmark tools like del.icio.us, so all the sites I bookmarks are added automatically to the custom search site list.  Here is a prototype of the site extraction part.  One stone two birds.  Hey, just created one of these custom search covering my sites.  Try it on the right sidebar.  Here is some interesting discussion from Matt Cutts.
