@Pangloss,
But then how will we know that we won a free iPod if we spent hundreds of dollars on things we don't want or need?
In all seriousness, it is great not having any advertisements. Even though FlashBlock kills most of the advertisements, there are still boxes that can reveal what may be waiting behind the door--and most people do not use FlashBlock. Thus, it is nice that a random computer illiterate person can stumble upon the forum and not be bombarded with advertising from the get go.
EDIT: Robert posted and tamed my last statement to: Well at least they are not bombarded with useless, irritating, and grossly obnoxious ads.
