Digsby is the ultimate software you will ever need for all your online socializing needs , With lots of Email providers, Social networks and Chat networks , I am sure you would be fed up switching between Gmail, Facebook, Twitter, Gtalk, Yahoo Messenger and  the list is endless , Even for a free person it’s too much Website’s and softwares to use for staying in contact with their Friends , but now you can do it all at one place and with ease, Thanks to digsby the ultimate "All in one Socializing client " (this is what I call it !!).

I am pretty much sure that Digsby would soon become a de facto standard for socializing as we have Firefox for browsing and Google for search .

Interesting Features Include :-

• A multi protocol IM client that lets you chat with all your friends on AIM, MSN, Yahoo, ICQ, Google Talk, and Jabber with one simple to manage buddy list.
