for those using dogcatcher, i tried it and didn't find it performing as good as beyondpod for podcasts. while dogcatcher is new to me, i don't see a stream function in DC? i have to download and play, with beyondpod i have both options, either download or stream, streaming takes 2seconds and you can even jump around pretty well for a stream, why stream? why not? say you want to jump on the treadmill fast/now and you have to d/l a podcast, depending on your gyms wifi/or your 4/3/G could take a while.
i did find DC's search for podcast feature way better than beyondpod, i don't know how you guys add feeds, i just search for it by keyword, there's no way i'll remember or get the rss feed from the website.
also for reading news sites or anything with feeds, Pulse is great, and has a cool widget too.
