One more thing I like about WordPress blogs is that even if you can’t find a feed button, the default feed is [domain]/feed. So for example, if I’m reading Law and the Multiverse and can’t find the RSS feed, I know I can point my feed reader to http://lawandthemultiverse/feed and follow any updates.
(Edited because I realized that although Pedagogy First! uses WordPress, it doesn’t use the default feed. Test links, then post. Doh!)
