What the hell happened to Yahoo! Podcasts?

Yahoo! Podcasts. Just a few months ago, Yahoo! announced this service -

I liked the ajaxy interface and the emphasis towards the new podcaster. When the CES conference was podcast exclusively on Yahoo!, I thought those guys were in business.

So what happened to them? I don't know anyone who uses Yahoo! for their podcasts. The few who don't use iTunes use either Juice or FireAnt. Yahoo! has a huge captive audience - myYahoo has done more, imo, to make rss mainstream than any other service, so why is this service not catching on?
