Here's something we've been tracking for a while, but it's bubbling to the surface today. It's been mentioned in passing in a few mainstream articles in recent weeks, so we give fair probability to the rumor, aired today by Wired, that Facebook is considering the addition of widgets to profile pages. This isn't part of Facebook Share, which has allowed the sharing of rich media content for some time, but would actually provide a permanent spot on profile pages.
If it goes ahead, the move would be the biggest blow to MySpace so far. The site is being criticized for its failure to embrace third party development, and hundreds of developers are looking for alternative places to embed their widgets should MySpace decide to block them. What's more, Facebook now has a great deal of momentum and a good reputation with developers thanks to the Facebook API.
