Remember its about the quality of your friends, not the quantity.
If you have 10 best friends, and someone has 1000 random friends that he/she never talks to, then surely you have it better somewhat?
I have 43 friends on facebook...and 212 on myspace, just cos i have more than 200 on myspace doesnt mean I talk to them all, most add me from meeting me once or so, some of which may have been bands/people adding everyone...
Basically, the number of friends on these sites doesnt mean anything
