Power Twitter is a Firefox add-on that Twitter users will like: it lets you embed Flickr Photos and YouTube Videos right into your Twitter stream. Another neat feature of PowerTwitter is that it expands TinyURL hyperlinks into their titles. I installed it today and I'm really impressed. Think of the potential: if Narendra, the 30Boxes developer who designed PowerTwitter as a side project, makes this into an open add-on that allows any web object to be embedded, then I think Twitter will indeed be a success story, instead of a temporary hype.
