How much should a pixel cost? Or better yet, how much should carefully arranged pixels that were once free cost? Well, more and more people are expecting their pixels to be free from the get go, that’s what attracted them to said pixels in the first place. Case in point, a new iPhone app for Twitter called Tweetie 2Â was recently announced to be priced at $2.99 a pop.Â You would think the twitter universe would be gleeful considering the rave reviews for Tweetie 2. Think again. When actress Alyssa Milano let her fans know her displeasure about the new cost of the once free app, she let the world know by tweeting out a big “Boooo”. This, in turn, created a lot of debate on the subject of giving you something for free, then charging you for it later. Another example of how pixel pricing is creating some buzz comes to us from the world of another social media giant.Â A recent Business Week blog post titled, “Facebook users can afford to pay” , suggests that Facebook should cash in by charging users for services rather than trying to generate revenue via advertising. But if Facebook starts charging for stuff that people once got for free, wouldn’t that create an exodus to an alternative social media network, like Twitter, for example? As Twitter becomes more Facebook-like, that might not be such a bad idea. Just think, you would only have to manage one social networking platform at a time and you could let the other one collect dust on your browser. Maybe it’s not such a bad idea after all.
