We're trying to pick up the slack where possible. In the summer we created the
Blubrry Powerpress plugin for Wordpress so there is at least one regularly maintained Wordpress podcasting plugin for the podcasting community to utilize. The last thing we want is to find podcasters giving up because their blog no longer works.
I'm sure you're right, we're going to see a pretty rough next year. It will be interesting to see who's left once the dust settles.
