www.orkut.com, world biggest social network, owned by google.
Well, its that much famous that people die to do it from office, even though having much of work load.
But sad to know, that most companies come to know about this and now blocked to surf the site from office.
Even though, few genious come out with many proxy URL to do ORKUTTING.
In some way if we see, then its good not to waste time on that during office time.
But yes, if free, no work in office, then its ok.
One which is quite famous proxy site is www.Kproxy.com
Best time to do orkuting is coming back from office and do it from home.
