Social is a lightweight plugin that handles a lot of the heavy lifting of making your blog seamlessly integrate with social networking sites Twitter and Facebook. Through use of a proxy application, you can associate your Twitter and Facebook accounts with your blog and its users. Once you publish a new post, you can then choose to automatically broadcast a message to any accounts authenticated with the overall blog or your current logged-in user. When publishing to Facebook and Twitter, the discussion is likely to continue there. Through Social, we can aggregate the various mentions, retweets, @replies, comments and responses and republish them as WordPress comments. Many individuals use Facebook or Twitter as their primary identity(ies) on the web. Allow your commenters to log in and leave a comment as that identity. Furthermore, they can publish their response directly to their Twitter or Facebook account.
