More on Talkdigger (can you tell I'm excited?). I checked out the feeds that it gives for a conversation that's being tracked, and was delighted by the level of discovery there. Talkdigger will automatically find pages that point to a particular conversation (e.g., a blog or a particular blog post). That info is available in the Talkdigger interface, or through the RSS feed of sources (that's RSS 1.0, of course). Here's a look at what the feed gives (viewed in Sage plugin for Firefox). I'll pick on Gardner Campbell again:

Here's a view of the whole list of sources:

What we've got is a feed of pages that link to Gardner Writes. The system isn't perfect--it picks up uninteresting links and links that from particular posts in the blog itself--but for a process of discovery it does a lot of work. The feed aggregator will open up many routes of exploration for other interesting sources. If I find that a source is particularly interesting, I would then go back into Talkdigger and add it to my list of conversations to track. Here, I'm interested in Access Technologists. I give it a peek, and see that Gardner Writes is on their blogroll with a link to the general Gardner Writes blog (not a particular post). That's not surprising, since the conversation in Talkdigger I started with is identified by the the URL to the general blog (as opposed to the URL for a particular post).

Let's go to another one way down the list, the podcasting lecture. That one includes a link right to one of Gardner's podcast readings. So I go back into Talkdigger and add both sources to my list of conversations I'm tracking. Talkdigger then gives me this:

Talkdigger gives the general blog URL for Gardner Writes as the related conversation (again, not the particular post) I might have preferred the link to the particular post since that would keep the relationships tighter, especially as one clicks on the related conversations to browse through them. It might be a little too easy to lose the conversation.

On the discovery side, though, the possibilities again open up nicely with the list of sources that link to that conversation:

Plenty to choose from there if you are looking for more about podcasting! And it's especially easy to browse through using the "preview" link.
