Facebook.com is the best social networking site ever I seen. Its services are good. Customer care support is also good.
Facebook is a good social site for communication. You can do voice call and video call to anyone in free on Facebook. And it is also a good chatting site for time pass.
There are many type of chatting option available in Facebook. The speed of loading pages is ok but if you want a speedy Facebook you need at least 3g or 4g internet connection.
