MessageCast, Inc. has a product called LiveMessage Blogger Edition which provides new post alerts for blogs (among other things). The full range of services is listed on their website but the free blogger Alerts allows counting of clickthroughs generated via LiveMessage and ease of setup. The basic utility of LiveMessage is to have the ability to route messages (alerts of any kind) to customers’ messaging devices by intelligently detecting the preferred (and active) mobile device to send the message to (thus eliminating Spam etc.). Consider this another way to distribute blog updates for your readers and in the process, pick up a bunch of new visitors to your blog.
