Two for the podcasting crowd, a new podcast search engine called Loomia and the AutoCatcher service from podOmatic that keyword-scans for new podcasts each day that you might be interested in.
Via Google Blogoscoped, in turn via Waxy, Loomia is a new podcast search engine that feels very similar to Odeo. Feed not listed? Add it here. You can tag podcasts and get recommendations based on what it thinks you will like. Keyword search for content or browse the tag-based directory.
Meanwhile, podOmatic offers podcast delivery to your MP3 player or computer using its podAmigo software or via email. Beyond that, the new AutoCatcher service lets you create a keyword search for matching content, then get a feed to you with all the latest matching podcasts.
To use this -- or just search for any podcast -- visit the site's search page. Do a search, and after searching, you'll see a "Use AutoCatcher to add this search to my iPod or mp3 player daily" link underneath the search box on the results page. Click on that, and you have saved the search and generated a feed link to use, if you've registered.
