To clarify, one of our community members (cmr) compiles these posts to summarize all the interesting developments in the language over the course of each week. It's an indispensable resource for those of us who can't devote ourselves full-time to Rust development (really, I'm in the IRC channel every day and I wasn't aware of half of these). It's also probably the best way for casual observers to keep tabs on the progress of the language in general. You can see the full archives here:

Thanks again, Corey!
