Using Feedburner, we can find out easily about how many subscribers we have. Not only that, Feedburner can also help us handling the bandwdith usage caused by our feeds. There is a service called Feed Compare. It’s a service to compare number of feed subscribers. This online tool can be used easily. Just provide the feed name (or full Feedburner URL) and click on the “Compare” button. Right now, it seems that it can only compare four feeds at a time.
