Have you noticed the ads?
An interesting thing I've noticed on this site, the ad bar to the side will often display advertisements relevant to (I guess keywords in) the article posted, although there will be other ads mixed in.
For example, I wrote about service quality a few weeks ago, citing a contractor who bid on building a fence. When I read that article, I noticed ads for fencing contractors. In the article I posted about Seattleites and allergies, I saw an ad for allergy relief.Same theme (and some funny results at times) throughout.
As an experiment:
Orthopedic Shoes worn to avoid bunions
Multivitamins taken daily to stave off rickets
Let's see if this works.
