Thanks for repeating this simple fact of life on the Internet. It
obviously bears repeating ad nauseam. A little bit of considerate
drafting of HTML avoids problems for lots of people, all of whom do not

Unfortunately, there is a proliferation of counters and the like which
have exactly the same adverse effect on bandwidth.
