Networking sites?

Hey just out of intrest what would you guys claim is the best networking site out there?

And how much you reckon it costs to make one? (top bebo's standards)

I was thinking of starting one up but would be really hard tog et going i think i would have to great loadz of profiles so aloads more joined

 

I would have to go with Myspace .

 

Myspace was one of the first ones i belive but how do these networking sites go about running everyones profile and having all the pages connected and all that sort of thing surely it must absolute hell to run unless its just a script?

 

yes.........Its a custom script made by an excellent programmers

Thanks
