Week 1 Muddiest Point

Admittedly, my muddiest point from the lecture was the blog feed. I've never really read blogs nor subscribe to RSS feeds (I'm assuming RSS feeds and the blog feed link that we're posting are one in the same) and I wasn't really sure what they are. I haven't done any research on my own yet to get to the bottom of this but I plan to. If anyone wants to help, I'd be grateful!
