Lot's of companies have blogs now—this is nothing new. And it's probably a trend that will continue to grow. As I was perusing Southwest Airline's blog, I coudn't help thinking about how on-brand the darn thing was. From the peanuts, to the large fonts, to the colors—it felt so right for Southwest. The blog even has a peanut favicon in the url. Then I saw it! That little logo at the bottom of the screen which tells you what design firm actually put this together (rd2). and it all made sense. Now I'll be curious to see if companies start trying to out blog-design eachother—similar to what corporate Web sites went through right before the Internet bubble burst.
