FeedBurner hasn't lost all of its friendliness, as one would be lead to believe looking at the change in the way their technical support operates. There are no more letters signed "Your Friendly Neighborhood FeedBurner Support Team" but not all is lost.
I had an issue with one of their features not working with Blogger, and I have submitted the error outlining where, how it occurs and the exact error codes Blogger returns.
What response I got from Blogger? Zilch, nada, nothing.
Whereas in the FB forum at least a so-called "Community Expert" responded to check my IQ (not in so many words), and after finding me sufficiently intelligent forwarded my error report to the FB staff, and a member of their staff responded quite quickly.
It would have spared everyone's time if the vetting process was skipped, and I would have felt better if not a "Community Expert" were the one cross-examining my error report, but a staff member from the outset (even if this member of staff is the same person as the "C. expert").
In conclusion, I believe FeedBurner has not chosen the most consumer friendly way to deal with the increasing strain on their support department, but they are still the most human branch of Google I have come into contact with through the Feedback or Contact us buttons.
