I'd agree with this argument that text advertising does a good job of 'selling stuff' online, but would argue that 'selling stuff' isn't everything that marketing is about.
I buy crap all the time, but that doesn't mean I'll buy the same crap again... that's what marketing is all about. Getting people to buy crap over and over. (okay, that didn't come out how I meant it to, but it works to get across the point.)
Back to the basics.
