Curious, has anyone who's using the new feed had the newest post (a dam failure in missouri) show up? The most recent post that shows up when I check the oil drum's rss is this entry. Perhaps it has something to do with it only having been 20 minutes since the post showed up.
It just showed up for me. One of the drawbacks of hosting the feed at Feedburner is that they ping sites only every 30 minutes, so that's the worst-case delay.
