I agree, and disagree with what Jimmy said in the previous post. It really depends what you are selling. Some items I have sold at a much higher price than others on Ebay by keeping my info on the item very plain and simple (easier to understand and read). Sometimes it seems that the more info, pictures and specs people add, the more clouded the information can become.
Also lets face it...the U.S isn't a 3rd world country by any means but the education level overall is much lower than most subscribers to this site and many ebayer's are poorly educated or do not speak english at even an average level (some I have found are near the point of being incoherent even within the U.S). Not only do simpler adds reach the less educated but they also present a clear and easy to read message for even the most educated who are sifting through tens or hundreds of ebay auctions trying to find what they need.
