Expect to hear a lot about RSS at Gnomedex. Not only is Scott Johnson coming, but Dan Gillmor plans on spending a considerable amount of time presenting arguments for how RSS is the gateway to the next set of killer apps (thank you, Dave Winer). Oh, and Nick Bradbury will also be in the crowd. You already know how I feel about this stuff. I received an e-mail earlier this afternoon from one Jeff Hardison: “I handle media relations for Amazon.com's Web Services initiative. I stumbled upon your AWS-based RSS feeds (and now subscribe to your music one). I'm writing to see if we could use your innovative use of AWS as a case study, should a reporter need one.” Here's a chance to get all your RSS questions answered – once and for all.
