Mash and men in Fezs

Rumours of Yahoo!'s social media pretensions were vindicated today when they announced the launch of Mash.
The service includes features common to Facebook, MySpace, and My Yahoo. According to TechCrunch you can load a set of modules onto your profile page and move them around drag-and-drop style. The modules include Flickr RSS, Ego Boost, Common Friends, MyMoshLog2, Blog Module (RSS 2.0), Asteroids, Astrology, PimpMyPet, Hover, Kaleidescope, Guestbook, and My Stuff.
Users are encouraged to edit each other’s pages. Each time you visit a profile page, you see new modules that others have loaded for you. TechCrunch says: "This capability certainly adds to the 'mashing' aspect of the social network. It is also appears as though Yahoo intends for users to mash their information together from across the company’s various properties, perhaps making Mash the main hub for Yahoo users."
I wonder if it is all a bit too late given the success of Facebook but given all those Yahoo! user accounts out there I suspect not - I await the email inviting me to join.
Meanwhile, things get more bizarre at Facebook as my son has just set up a new group there called: Top Hats and Fezs: Man's Greatest Invention - that explains the picture anyway.
