One of recent update from orkut that now you can search your friends directly from the home page.

Now a days orkut is rolling out new features daily. One of the hot feature is you can search your friends from your home page . A search button is on the above of my friends list (see image). As before you have to go to yours friends page and have to type the friends name and hit enter. But this widget suggests the friends as you type 2 or 3 letters.

Other recent feature added by orkut are mentioned below >>
> Scraps text inside email.
> Stop others finding you on orkut by searching your email.
> Share photo with only selected friends.
> Chat with your friends right inside orkut page.
> Scheduled events , create and invite your friends.
