I humbly disagree. I was waiting for the site to "finish loading", and when I realized that it had, I was delighted.
However, when posting a link on a site that will likely generate hundreds of hits (3% of which might click the ad), its only fair to THE COMPANY to post to their main site.
Everyone should promise to buy whatever product is being advertised or at least convince themselves that their brain patterns have been changed so that they are more likely to buy the product in the future.
It's only fair to WaPo.
I don't think it's really that big of a deal. If it was a subscription service we were all bypassing without paying that's one thing, but this is just another page on their public website like anything else.
If you don't want people to see it, don't publish it online.
