Taking a cue from Twitter and embedded tweets, Facebook (s FB) says it will allow folks to embed blog posts from Facebook on blogs and other websites. It is a way for the company to extend its footprint across the web and at the same time try and steal conversational attention from Twitter. Facebook is largely a walled phenomenon and often lives outside of the open web. These embeddable posts also include hash tags, another Twitter innovation Facebook is trying to appropriate.
