Google Reader makes it easier to add RSS feeds to your profile
The Google reader team have been working on ways to simplify adding RSS feeds to your Google Reader profile. There are a couple ways now to do this (outside of logging into reader and entering the address (or site) and searching for the feed that way. First up is a little tiny button with a plus sign and the text “add to Google”.
There are also two bookmarklets which I think are more interesting. These are made to put in your browser toolbar and then a click on the bookmarklet hunts for and subscribes you to the first feed on the page, or shows what feeds are available (depending on which bookmarklet you use.) More detail at the official Google Reader blog link above.
