Just like aggregators such as Friendfeed, Rediffmail has launched its free feed service where you can directly get all your updates on your @rediffmail account from Orkut, Facebook, Hi5 and Linkedin social networks. Recently Rediffmail launched its unlimited free storage email.
Though aggregators are not new, but for those using orkut and facebook this could be very useful. So if anybody writes a scrap to you or scribble your wall in facebook you’ll directly get the update on your email. Not just email, this is also true for any other updates like changing profile pic, status etc.
Sending updates to mail is also not common amongst all aggregators. This service will be extremely helpful for those residing in India or Brazil as they have the highest number of orkut users in the world and facebook is also catching up at very high pace there.
Also note that you need to enter your account information for all the four social networks which is quite safe according to their terms of use.
If you never get time to check all these social networks, then this service could be of some use to you. And if you are using it already then do let us know about it.
