Orkut is one big boon to help track down old acquaintances and keep track of current ones. The concept of communities, friend groups, scraps - it's all cool.
However, there is one feature Orkut really needs to discontinue: the ability to change one's own display name. When your friend list is over two hundred and you want to search for a particular friend in your list, there is no quick way if the person has a display image of a vague illustration, a car or hopeless scenery and a display name like "Lara has retired", "Saurav da is back", or some philosophical crap about life/love. Sheesh!
Also, a special brickbat for those who use the scrapbook feature as an instant messenger! What pain and inconvenience (has become so fashionable!) when there are so many instant messengers doing their jobs so well!
