Although I won't judge these efforts too harshly, since I haven't signed up to see them, I can't quite understand the point. Perhaps if I were attending a campaign event, it would be nice to have the time and address on my phone. Other than that, wouldn't it just be easier to get information by e-mail?
Maybe I'm just an old fogey -- I was born more than two decades ago -- but I don't need more mediums of communication. Rather, I'd like more interesting, informative, honest messages, irrespective of the medium. If the 13th Floor's experience with podcasts is any indication, public officials have a lot of catching up to do in that regard.
