A few days ago I created the first implementation of the idea of TweetBacksand published it to my blog. This is beneficial for a variety of reasons:
Twitter tends to be a quicker and easier way for users to comment on and share content that they like; by allowing your users to join in the conversation via Twitter, you’re opening the door to a whole lot more feedback.
TweetBacks also opens up the possibility of a Twitter user’s avatar and username to be displayed on a potentially popular post, creating more incentive for users to spread your content for you. Reputation and “fame” is always a great motivator; just think of all the “First!” comments you used to see on Slashdot.
As my research has shown, social proof is an important factor in how “viral” your content becomes, and displaying a list of individuals who liked your content enough to spread it is a powerful way to tap into that.
TweetBacks also form a sort of implicit call to action for your readers to hop over to Twitter to spread your content. As soon as they read your post, they’ll have that idea brought to mind because they see a list of other people doing it.
