When I started my BleedYellow blog, I wanted to allow my feedburner subscribers to be able to get updates from both BleedYellow and BlogSpot. I plan to continue contributing at blogspot for non-technical posts.
However, I've had some issues with this....
From initial research at feedburner, I saw that Yahoo! Pipes and RSSMix were recommended to accomplish this. So, I tried the Pipes first, but feedburner couldn't recognize the feed. Then I tried RSSMix and it seemed to work really well for a couple of weeks. But then I noticed that I was no longer seeing updates. No good. So I looked around a bit more and found a slick site called XFruits. But someone pinged me stating that some of my posts were coming through as 12/31/1969! So then I found FeedDigest. It initially seems to work alright - quick updates, correct dates, etc.... But apparently it doesn't handle the publishing of apostrophes in the title of my BleedYellow posts...
I've already posted that there are some issues with Connections feeds through PlanetLotus. So I'm not entirely sure that all of the issues are the fault of the feed mixers or if there is some minor bug with the feed from Connections... 
Anyway, off to watch Terminator: The Sarah Connor Chronicles season finale!
