Well, I just learned one bad thing about PalTalk. They only allow you to use Paltalk Express for 5 times for free. Then you either have to either live with the advertisements in Paltalk Scene, or pay $39.95 a year for ad-free access to Paltalk Scene and Paltalk Express. I think I may go ahead and pay the money. Paltalk seems to be a powerful tool for communication; despite the cost, it is still better than Skypecasts in many ways.
