I find Big.com clever. It’s just another search engine, but the fonts are bigger. Fun twist, and with a short URL, sure to get some traffic. Of course, the Terms of Service are not in the bigger font. Hmmm…
This is all part of Idealab, as is the current Snap.com. Although the results for Big.com come from Ask.com. Got that straight? Enough three and four letter URLs for you?
