If you like to stockpile weird and fascinating facts, you should head over to factslides.com, which describes itself as "Addictive, creative, colorful and animated slides of amazing facts you didn't know!" It also claims its posts are "strictly verified and well sourced." While we can agree with the first statement, we leave the second open, as their sources are as varied as Wikipedia, the English Daily Mirror, Time magazine and McDonald's Australian corporate site.

Designwise, Fact Slides could not be simpler or easier to use. Each "page" states a fact in bold type. Arrows move to the next or previous fact; a timer adjustment can be used to make the site a slideshow. The site's bottom has a scrolling bar with topics to click on to discover facts about 10 random subjects.

Each page also has a clickable source, which leads to where Fact Slides found the information. Some sources work well, others not. When we checked the source for "It would take 1,200,000 mosquitoes, each sucking once, to completely drain the average human of blood," the link led to a Digital Spy page with nothing about it. A search of Digital Spy returned no results. Through Google, we tracked the statement to an August 2007 Discover magazine online story.
