AdaptiveBlue, a company founded by Alex Iskold a contributor to Read/Write Web, offers a couple of different ways to create a smarter browsing and personalized experience by connecting users with an array of services.
By leveraging Mozilla's platform AdaptiveBlue has created BlueOrganizer, a Firefox extension that makes it easy to collect, manage, discover and share information matched it to real-world things like movies, wine or electronic gadgets. BlueOrganizer's wide spread utility makes it difficult to pinpoint a concise product category but it does offer users easy access to a number of content-based utilities. BlueOrganizer up by saying it is a bookmarking product that offers service related information based on what you are looking at (both past and present) on the Web. Users can use BlueOrganize to save, rate and organize the sites and items that they like. If you are too lazy to bookmark you can turn on an "Auto BlueMarking" feature that automatically saves pages a user has visited a set number of times. This feature could come in handy but can be turned off by the user if found to be cluttering their saved items.
AdaptiveBlue also offers SmartLinks as a way for publishers to surface links to relevant information. SmartLinks take advantage of affiliate programs to offers publishers a monetization option that is similar to putting sponsored links on a site. In similar way that Sphere's "Sphere It" widget adds related blogosphere content to an article, SmartLinks add value to an article by connecting users with other relevant information about a specific item. My only concern with SmartLinks is the time it would take a publisher to add them to their content, since it currently is a very manual process. AdaptiveBlue might address this in a similar fashion to "Auto BlueMarking" by integrating a simple rules system into existing publishing platform thus removing the extra work which could be considered a barrier of entry.
Finally, AdaptiveBlue offers something called a SmartLinks Badge. Publishers can use the badge to display items that they like and want to share or recommend with their readers. You can configure a SmartLinks Badge here. Of course, you can hook your badge with affiliate programs to potentially generate some revenue from your favorite items.
Bottom-line: AdaptiveBlue offers a couple of different ways of connecting you with relevant information about a particular item via an link on a page, a page badge or a web browser plug-in.
