Just got this in my email:

AlltheWeb.com is all new. The freshest, most comprehensive Internet search engine is now refreshed every nine to twelve days--more than five times as often as other search engines, ensuring you have access to the most up-to-date results available. Search photos, music and html files in the same query. Plus, AlltheWeb.com features:

Integrated multimedia, MP3 and FTP search results
Site collapsing
Automatic Search Tips built into your query
More intuitive, user-friendly interface
9 to 12 days is pretty quick considering they are still free. I wonder how this will change once they are charging for inclusion.
