Multimedia Trapping - Information Trapping: Real-Time Research on the Web - page 172

his is a great place to get an overview of what a podcast ofers in its episodes.
he resources we've just examined are great for showing you what podcasts
are available, but you might not want to subscribe to entire podcasts. Instead,
you might just want to hunt for episodes that are relevant to your topic of
interest. You can do that with keyword-based RSS feeds for podcasts. here's
even one search engine that lets you search the audio of podcasts!
For the resources that follow, all you have to do is run a keyword search
and save the RSS feed for that search. You then add the RSS feed to iTunes
as a podcast. Bingo. As new podcast episodes match your keyword, those
episodes will be automatically downloaded to iTunes. hat's all there is to it!
You can catch up with your information trapping by listening to podcasts
as you work out at the gym.
Monitoring podcasts by keyword
del.icio.us may sound familiar to you—wait a minute—isn't del.icio.us
a tagging site? Yes! And guess what, you can search for the tag podcast ,
along with any other keyword in which you're interested ( del.icio.us/
tag/podcast ). So the URL would work if you're just looking for podcasts in
general, or you could add a keyword to it, like this: http://del.icio.us/tag/
podcast+reggae .
Monitoring Del for tagged podcast episodes doesn't work quite as well in
iTunes as the two other resources we look at in this section (there's no guar-
antee that a Del user is going to link to an actual podcast as opposed to the
podcast's Web site). But this trap does turn up some very unique inds. Try
it for some of the more general keywords that are getting you too many
results in other search engines.
Blogdigger Media (blogdigger.com/media/) is a blog search engine, but it
also ofers a lot of unique searches as well, like this media search. It doesn't
search just podcasts; it can also search video and images too (make sure
those options are unchecked if you want to focus only on podcasts). Blog-
digger doesn't seem to have as large a database as some of the larger search
engines like Technorati and Feedster, but it ofers a number of multimedia
searching options.
PodZinger (podzinger.com) is very cool. Up to this point all the search
engines we've looked at let you search for keywords within a description of
