Yahoo pipes

I'm trying to unite all my blogs into one single feed for anyone who might be interested. So I went on to try Yahoo pipes....


It looked fine. The result also turned out to be fine on the yahoo preview page. Same reason as before, I wanted to use feedburner as my final feed output. Who knows if there will be a google version in the future or that Yahoo pipes stopped functioning. However when I tried to redirect the feed to feedburner, it gave me errors. It seemed to me that the feed doesn't meet the standard strictly. Oh well. I then tried to subscribe it in google reader, but for some reason the date is completely out of order....is it cache problem? I guess I'll wait a few more days and see.
