"Sponsored Post" WTF?

Over at LeftLane News, I read a glowing review of Toyota safety features.  I wondered why they were basically repeating Toyota's new marketing campaign, until I saw the tag "Sponsored Post".

Guys, write your own stuff.  It is bad enough that readers have to wade through banner ads, side panels, and on some sites, popup ads.  If they have to learn to ignore parts of your main feed, they'll get annoyed and start to tune out.

I don't have massive readership, but for the few readers I do have, I can promise this: any posts you read on here were written by me, with some thought.  There will be no sponsored posts.  No ghostwriting.
