Google Reader Subscribe Book Marklet (Favelet)
To use, drag the URL to your bookmark toolbar. When you find a blog you’d like to subscribe to, hit the bookmark and it’ll take you to Google Reader and offer to subscribe to the feed (if Google can find one).
Google Reader’s new search can find the rss feed when you search for a blog’s URL. This book marklet takes you to the search results for the current page. Makes subscribing to blogs in google reader way too easy. It seems to work equally well from pages withing a blog as from the front page.
