Switchpod is a podcast hosting service claiming to be a complete podcast hosting service, offering you unmetered bandwidth, the fastest speeds, the most detailed statistics and the best promotional opportunities.
The site doesn't really show me much that says they're the best etc. They have a pitiful directory of the podcasts they host. In fact, browsing the directory I'm finding many of their listings go to dead websites.
They offer free podcast hosting, so maybe some people have signed up, then they lost interest and never deleted the account with switchpod.
