Yahoo! gets social
There are a slew of options - photos from Picasa, SmugMug, Webshots and Zooomr; StumbleUpon, Furl and Ma.gnolia bookmarks; blog posts from Blogger, Bloglines, Travelpod, Tumblr, Vox and Xanga; Last.fm and Pandora music playlists; your latest Vimeo and YouTube favorites; Twitter tweets; Yelp reviews; your PowerPoint presentations from SlideShare; and your book recommendations from Goodreads.
To be sure, some of the bigger sites are missing from here - no Digg or Reddit, no Delicious, no Flickr (even though Yahoo! owns Flickr).
All you have to do to add these is to head to your Yahoo! profile, click on "Updates" and then "Share More." Choose the sites where you have accounts, load up your info and presto! Your social media profile is shared in yet one more place. You can control who gets to see these updates through the (logically named) "Manage my updates" button on the settings/updates tab on your profile.
