I wouldn't want to be featured on this site: YourLogoMakesMeBarf.com - I could probably send a few examples that I work with daily as examples to them though...
YourLogoMakesMeBarf.com is intended to be a humorous look at what can go wrong when an unskilled person (your neighbor’s brother’s uncle’s friend anyone?!) designs a logo. Good logos require time and involve great forethought. A good logo should be a financial investment but also something that will benefit the long term growth of a company.
So leave the designing to the designers and browse through some of these fine examples of what not to look for in a logo. Barf bags recommended.
