Feedburner released their new stats "system" today. It's much nicer for sure, but for me the most interesting new feature is tracking enclosure downloads (= podcast audio downloads are tracked now), a great feature for podcasters. Make sure you check "Item enclosure downloads" in Analyze -> StandardStats (or Analyze->TotalStatsPRO if you have PRO stats enabled).
In the meantime, I'm playing arround with FeedFlare API to create my own "flares".
These guys really get it.
