I like that I can change my feeds as often as I want and set them to expire at different dates. The customer service is also very helpful when having issues with the system. Sometimes can be difficult to export all of your feeds if you have thousands of them. It's worth it though because you are able to be so granular in who you send your feeds to and what you do with those feeds. I've also discovered some new sites using this tool which was great! I highly recommend this software. I'm solving the problem of not being able to keep up with changing feeds quickly and easily.
