Trackle is like RSS for your world. When you sign up on the website, you're prompted to enter things you would like to track. And there is no shortage of categories to choose from. You can track neighborhood crime and home values, stocks, Facebook notifications, sports, music releases (from iTunes), news (from CNN or NY Times), top YouTube videos by category, birthdays - even high pollen days. And the list goes on and on. You can choose to keep all alerts within Trackle's system, or delivered to your inbox.
There are also some interesting business "tracklets." Product reviews (from CNet), a price drop watcher, Trackle me on the Web using keywords (powered by Google), use any keyword and track them on blogs (also powered by Google and good for reputation monitoring, and keeping an eye on competitors). More subtle uses like tracking holidays might be good for planning email promotions, and LinkedIn updates can help you keep tabs on contacts.
I ran it through a test overnight, and the results were quite impressive. Birthday reminders were right on time, and everything I followed showed up in my Trackle inbox as promised. The advantage here is that you can pull in infromation and have it all in one place, in a delivered, easy-to-manage format. The disadvantage is that you're limited to Trackle's sources. The more sources they add, the better this service will be. And I would like to see a feed reader, so I can get all of Trackle's great stuff, plus whatever else I want. Then I could truly have one place for all my daily informational needs.
