we are matured enough naman siguro para mag-isip ng tama at mali. Its our own choice whether we wanted to spend big or small amount of money just to get what we wanted in this so called facebook apps or FB games. After all we are using the site for free, and even the game apps are free. There are some portions of the apps that you need to use money. FB owners also needs to earn to be able to improve and continue developing their site and also to pay for the staff. Hindi naman sa facebook lang gumagamit ng pera di ba, daming online games na kinaadikan ng mga tao like SF, Audition, Highstreet5, etc... dito mga customers lakas mag e-coin sa SF.
