Besides the funny names and bad spellings, one hallmark of Web startups over the past few years has been the creative use of logos. Often you know a startup by its logo more than by its name, especially if it is for a Web app whose site you don’t actually visit that often. Instead, the logo appears as a favicon in your browser address window, or as an icon on another site.
