Web filter filter: I seem to remember a link to an NYT article that just contained the full text of the article in nice big letters, with no graphics, banners, or ads. It was fully attributed, with links to the original, but it was much more pleasant to read, especially for a long article. Is there a website that will filter out the clutter and provide links that can be forwarded?

I prefer products that don't require replacement parts (e.g. gadgets with rechargeable batteries, bagless vacuum cleaners, etc.). I'm currently in the market for an air filter, but they all require replacement filters, and I can't find one that operates on the same principle as a bong. Do such magical appliances exist? Is there a good reason why they shouldn't?
