At first it was amusing to watch a few video interviews on the net, but now it's becoming absurd. Instead of spending a couple of minutes to scan an article and pick out any salient points, I'm expected to set aside an hour to watch a video of a couple of talking heads - no thanks. Audio-only podcasts are just as bad, you can only listen to so much gumpf on your way to work. YouTube videos of someone's baby doing a silly dance are amusing, YouTube videos of some geek talking into his webcam aren't.
The reaction is starting to happen,(read the comments), though as long as venture capital continues to dump money into semi-literate 'Web 2.0' companies things aren't going to get better. Yes, in many ways it takes more effort to transcribe an interview or express an argument properly in writing than it is just to dump a video recording onto the web. But ultimately all this does is shift the effort away from the people looking to profit (blogging for pay from ads) and onto their audience.
