I love Autoblog, and it is one of my first reads every day.  One thing Autoblog does is serve up a lot of ads, including one at the top of the page.  Today I noticed a “Comment on this Advertiser” link directly under the Suzuki ad.  Sure enough, clicking on the link brought me to a comments page asking me to “Please add [my] comments to inform others and help this advertiser improve their offering.”  

Way cool!    A great way for an advertiser (Suzuki) to get blog-like feedback without actually doing a blog itself.
