TwitterFeed broadcasts an RSS feed to Twitter. The Facebook Twitter app streams your Tweets (note: only those not beginning with @) into your Facebook status updates. The ShareThis button is embedded on a Web page and allows visitors to share that page across many ( many ) social networks. Publish 2 is a Web-based bookmarking and link sharing service. It remembers Web pages for you and lets you share them if you want. It also allows to to broadcast the pages your sharing on your own Web page. Delicious is similar to Publish 2, but it's open to anyone (not just journalists) and has less options.
