Wouldn't it be nice if I could post a code sample, like the one about the multi-sorting comparer, and instead of doing a copy and paste of the code into your own code file, you could have your aggregator (you're using an aggregator right?) pull the file down automatically?

Or what if you went to a user group meeting, and instead of the presenter telling you where you can download the sample code or presentation, you could pull it down from his or her blog when he or she posts it to their blog?

I think that's going to be the use for "podcasting" that'll make it mainstream.

Now, I just need to hack up b2evo so it'll support enclosures, then modify my blogging tool to support uploading of attachments and posting of enclosures. Then I can attach my code samples to my posts.
