The thing that drove me to the app is the seamless integration between the website and the app itself.  I can hop onto the website, create an account, import my OPML list of podcasts from iTunes and BAM - there's my stuff!  I can the go organize the podcasts into folders on the web, and given a local client I can play it anywhere I am! Simple!  I have to admit that the website was fairly easy to use - there were some hickups - like using a remote control for putting podcasts into "channels" as opposed to a "folder" but those are more or less frames of reference. The UI on the website could be improved, but it ain't horrible.

Most of my problems are with the iOS client, which have made me not want to use the service on my iOS devices.  Here's a quick laundry list of major FAILs

There are also some minor UI fails that were annoying but easily fixed.  The tab for instance that you tap on to reveal the playback buttons doesn't support drag-up and drag-down.  I was confused as to why this tab wasn't coming up when I was dragging it.  Some of the UI seems to be built for a mouse-based UI interaction while other UI elements seem to be somewhat thumb-touch-based.

The final thing that was kind of annoying was that audio playback didn't start up quickly enough. There was always lag between pressing "play" and the thing actually starting.

I feel like this app would be great if it left playback to Apple's built-in app, and it just handled the podcast retrieving and loading.  For the time being I won't be using the app since it was just one huge aggravation (in-between listening to podcasts). It will however stay on my iOS devices as a reminder of what podcasts I've subscribed to, and to keep an eye out for future developments.  It has potential, but the iOS client is just not there yet!
