What would you do if Google did not exist, or Yahoo, or Ask, or search on MSN or AOL?  As it turns out, there's more than 100 other search engines out there.  Some focus on a specific niche like video, health, or blogs.  Some are trying to improve the whole search interface by displaying results in a more visually intuitive manner, like Quintura or LivePlasma.   

The AltSearchEngine blog is encouraging Web surfers to give up the major search engines just for today and try one of the smaller ones.  Here are some you can start with (the full list of 100, courtesy AltSearchEngine, after the break—list your favorites in comments and tell us why):
