Here is another Collaboration Feature from Google. Google has introduced a new Gadget maker product for iGoogle (new name for Google Personalized Homepage). The users without having any programming or web design experience can create Gadgets and share with community or other iGoogle user. The Gadgets are as simple as filling out the form in the predefined 7 templates:
• A Photo gadget which is designed to share a series of photos
• GoogleGram gadget that display a new greeting message for every day of the week
• Daily Me gadget which will show what you’re currently doing, as well as quotes, what’s on your mind etc.
• Free Form gadget that as the name suggest will allow free flow of information, image text layout background colour
• YouTube Channel gadget to share good videos on YouTube
• Personalized List Gadget to basically present your list of items. It could be list of your favorite songs, a list of items to buy today etc.
• Personalized Countdown gadget is more like a reminder to any event, happening with a countdown
Apart from this, it provides option to update the Gadget and re-publish so that it gets updated at the other end.
Pretty neat way to bring people togather !!!! 
But few things to watch out for:
• Updation at receiving end took a pretty long time to get refreshed with updated information
• No intimation whether the iGoogle user has added your Gadget or not
• If the Gadget creator deletes the Gadget, will it get deleted at the other end?
• A way to establish two way communication rather then just one way for now
