Browser Support: Built-In RSS--IE 7 Beta 2 vs. Firefox (With Sage) vs. Opera
Among Web browsers, Opera has long been ahead of the curve in supporting RSS feeds natively: It easily adds new feeds and notifies you of new items. But Opera's horizontally divided two-pane display looks a bit bland and lacks inline image support.
Firefox's Sage plug-in is a little rough around the edges. Adding a Feedburner subscription requires cutting and pasting a URL, for example, and while Sage can treat a favorites folder as if it were a set of feeds, that works only with one folder. But once your feeds are setup, pressing <Alt>-S displays the sidebar and an attractive two-column view showing each story and images in its own box.
It's been a long time coming, but the native support in IE 7 Beta 2 works quite well. Feeds are integrated with favorites, and though the feed-by-feed, single column look may not be the most efficient, it's more eye pleasing than Sage's or Opera's. You can search each feed and reorder stories by date, title, or author. If its feed detection improves, IE 7 could win over newsies and newbies alike.
