Well this has seemed to be all about Widgets so staying on topic, take a look at Widgipedia.com.  The site which officially launched today combines widgets from Widgetbox,  Yahoo, Musestorm etc.

The funny thing is you would think that such a site would contain loads of quality yet the lack of quantity and quality was surprising. However the concept is good (yet the design is lacking) and I am sure it will grow with time.

One last note.  I mentioned that it uses widgets from Musestorm yet I couldnt find any.  Let me know if you could.
