Telecommunication is the transmission of information over significant distances to communicate.In earlier times, telecommunications involved the use of visual
signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as coded drumbeats, lung-blown horns, and loud whistles. In modern times, telecommunications involves the use of electrical devices such as the telegraph, telephone, and teleprinter, as well as the use of radio and microwave communications, as well as fiber optics and their associated electronics, plus the use of the orbiting satellites and the Internet. The world's effective capacity to exchange information through two-way telecommunication networks grew from 281 petabytes of (optimally compressed) information in 1986, to 471 petabytes in 1993, to 2.2 (optimally compressed) exabytes in 2000, and to 65 (optimally compressed) exabytes in 2007.

I am thinking about trying out one of the services and there are a lot more of them than I expected. I see "Fring", "Paltalk", "Nimbuzz", "Tango" and "Skype". Some of these look like mainly straight voice/video-calling, but others (Paltalk in particular) are more like conference calls, and even "CB Radio" - ish.
Aside from "Skype", which I think is fairly straight forward, has anyone tried any of these? Or do you have any opinions based on anything you have read?
