[Air-L] web2.0 discourse, logo and taglines

Hi all Have any of you or do you know of some who have published on the rhetoric of web2.0, especially the way these companies uses logo and taglines as a way of branding themselves. Think taglines like Flickr’s ”flickr loves you” or Google’s ”don’t be evil” and other tacky lines (pun intended). Cheers, Soeren Moerk Petersen
