app.yaml to allow
brenthuisman.net (sans hud) to access the proxy. I rediscovered FeedEk, the script I had used before. It has changed to using Yahoos YQL, which turns out to be a powerful to access and incorpated data from all over the web onto your own website.
A few modifications later, and Feeds is back. Noice. One downside: it appears to choke on RockPaperShotguns feed, so I had to let that one go
:/. I also discovered the are a few Bostons Big Picture feeds out there, of which only one has a nonmalformed feed. Apparantly Googles feed proxy did some cleaning up as well (and it still seems in operation, although the deprication warning is still there).
