The problem is not under-usage per se, but hype. Caldwell's soapboxing about Twitter's failure to live up to its potential raised expectations, but didn't provide a solution to the chicken-egg problem. I'm sure Caldwell & co can build a great API and app platform, but that all becomes relevant and compelling only once App.net can grow a community a respectable fraction (1%?) of Twitter's size. Of course, as noted elsewhere, it's too early to pass judgment - but it's also a good reminder that unless you like throwing around $50s (http://ihave50dollars.com/ http://ihave50dollars.com/), App.net won't matter to you for a good while yet.
