overly formal, corporate-speak

It frustrates me when  business Web sites and correspondence use overly formal, corporate speak because if the website is meant for the customer why speak in terms that the customer can understand. This often leaves the customer confused and still uninformed. I think that many companies still speak this way even though it is uneffective because they feel that it has to sound professional and and educated and maybe they are unaware how to communicate their point in a conversational way and still feel that they sound as such.
