I've known this was coming, Matt told me about their RSS aggregator when he told me they were supporting rssCloud.
So theoretically, I should see this update over there immediately because I'm subscribed, and of course scripting.com supports rssCloud.
And of course it's good news that Wordpress is embracing RSS fully, as a way to connect reading and writing. It's what I wish Twitter and Facebook had done from the beginning. They said it wasn't possible. It's good to see that Matt & Co didn't fall for that.
Update: Apparently you can only subscribe to a blog, not to a feed. I have quite a few feeds that don't have blogs. No reason to. Here are a couple of examples: NYT firehose, Hacker News firehose. Thee are two of my most-used feeds.
Update: I tricked it into subscribing to Hacker News by creating a pseudo-blog "wrapper" for it and asking Wordpress to subscribe to it. However, it did not like the wrapper for my linkblog. Weird and frustrating.
