Feedburner and TypePad will announce a partnership on Thursday that will allow TypePad users to automatically redirect their existing TypePad RSS feed into Feedburner. Until now, if a TypePad user wanted to transfer RSS subscribers to a Feedburner RSS feed (and take advantage of Feedburner stats for those subscribers), each subscriber to the old feed would be required to change their subscription to the new feed. Since subscribers have little incentive to do this, many Feedburner publishers end up managing multiple RSS feeds over time. This partnership will save them the hassle of doing that.
Look for more partnerships like this from Feedburner over time. Details on the partnership are here.
