Bloglines an online RSS reader (recently purchased by Ask Jeeves which in turn is being aquired by Barry Diller’s IAC/InterActiveCorp) announced last week that Bloglines is First to Go Beyond the Blog with Unique-to-Me Info Updates. What does that mean?

Starting today, people can track the shipping progress of package deliveries from some of the world’s largest parcel shipping companies—FedEx, UPS, and the United States Postal Service within their Bloglines MyFeeds page. Package tracking in Bloglines encompasses international shipments, in English. Bloglines readers can look forward to collecting more kinds of unique-to-me information on Bloglines in the near future, such as neighborhood weather updates and stock portfolio tracking.

You can check out the package tracking here.

With IE7 rumored to have a built-in RSS reader, services like Blogline’s package tracking and My Yahoo!’s RSS integration, RSS (or some type of syndication… why do we have RSS, Atom, et al.?) sure seems like it will be mainstream pretty soon.
