Here is Google’s Google Wave Overview Video Via: LifeHacker

If you were lucky enough to get into Google Wave this week, you probably wondered “Now what?” when you found nobody to wave with. If that’s the case, here’s the first search command every Wave newbie needs to know: with:public . If anyone on your Google account’s Contacts lists also has Wave access, you’re set–but for some folks that’s no one, or just one person. I’ve gotten a few waves from people saying “I have no one to talk to, and you’re the only one on my list.” Entering a search for with:public returns a huge moving sea of public waves anyone can read and update.

Looks like We got at least one close match of a  feature of  Windows 7 Pin to taskbar. Chrome  tabs have got a Pin Tab feature which not only lets you make the tab stick but also lets you reduce the size of the tab to the favicon. This is how it works exactly : Right Click and select Pin Tab. In order to remove it from the pinned state, just right click and click on Pin tab Move it after the first unpinned tab and it gets a bigger tab i.e. Unpinned.
