a logo is something that is designed to work on EVERYTHING. its designed as a vector, so it can be scaled properly. it should work in only black and white, as it would be used on letterheads, added to products, and you will never know all the forms ahead of time. it needs to work on different mediums. unless you are running some fly by night operation or literally do not care about how you are represented, its a very, VERY important part of your business. It is how the world sees and recognizes you, and needs to convey your ideals. anyway, it's not meant as an attack, just a heads up on the quality you can expect.
