The main new feature in the release is support for tagging of feeds, blogs and posts:
Weâ€™ve integrated an incredibly easy way to tag articles and feeds using the Attensa Toolbar for Internet Explorer. Tags are simply keywords you add to add context to RSS feeds, articles, Web pages, blog posts, photos, even music you discover online.
The new tagging feature can be used in Attensa to keep feeds and articles organized but it also works with Del.icio.us. Del.icio.us is a great way to keep track of anything that captures your attention on the Web and to share those things with people with similar interests. When you set up your bookmark page on Del.icio.us, not only can you see the pages youâ€™ve you tagged, you can also see related articles from other people who tagged the same pages or used the same tags as you have. Since every Del.icio.us page has an RSS feed, you can also subscribe to feeds based on a given subject, user, URL, or tag. Itâ€™s a pure attention stream that you can explore.
You can add tags to articles and access them using a pull down list using the Attensa Toolbar for Internet Explorer. When you tag articles with Attensa your bookmark list on Del.icio.us is updated and synchronized automatically. With the addition of tagging, Attensa gives you a set of tools for organizing your feeds and articles. Categories let you create a hierarchal structure using folders to keep feeds organized. Tags give you a more free form tool for keeping articles organized and they connect you with the del.icio.us social network.
Attensa is aggresively adding features to compete with other readers and has an excellent product suite. However, some (including Jeff Nolan) have stopped using Attensa’s Outlook product because of reported difficulties in making these third party applications work with Outlook properly.
