I have enabled FeedFlare in my blog feeds. FeedFlare is a service provided by Feedburner to enable more user action to the feeds, like email this, tag this, technorati links, etc. If you are reading this in your aggregator, you have already seen them in the bottom of each post.

There is an apology to you. In enabling this service, all the posts are marked unread. This is a one time pain for you.

See press release and Feedburner blog for more detail about this service.
