What do you think? Should Saturday mail service continue?

People in the industry call it the "float" or the "drip." Marketers drip direct mail into the flow. Billers talk about floating bills. Companies get paid a lot of money to know when to drop come-ons in the mail so they reach people in St. Louis and Seattle on the same day.

The Postal Service's five-day mail proposal -- stopping Saturday delivery -- has the potential to muck up a rhythm in place for decades. So here's the query: Do you notice certain pieces of mail come on certain days? Do you like to mail cards so they arrive on Saturdays? If your business does direct mail, what day or days do you target? How will a five-day mail week change your own mail patterns?
