Social Bookmarking Blogs

What is the best all-in-one widget to send email, RSS and bookmarks to Blogger blogs?

I keep coming across add widgets to my Blogger blogs social bookmarking, email and RSS subscriptions, but always seems to do best all-in-one widget in general other blogs. Does anyone may recommend a single widget that allows people to subscribe to e-mails, RSS feeds, bookmarks and add Google, Yahoo, Facebook, Twitter, Digg, etc. etc etc? Something Slim, understandable and practical.
