Is making clones bad?
code_devil: I think its fine. Look at even the current social networks in English itself.Dating Sites ---> Friendster --> hi5 --> Facebook --> Orkut                                               --> Bebo

                                               --> WAYN

                                            --> LinkedIn

They all started with the same base, a database of people that interact.Again, the App development platform was started by facebook and now everyone else copied it. So, once you clone it you can always give it your own unique flavor with time.
