Your argument is a truism: that any competitors don't have the budget/user base. Well duh, FB is by far #1 in both of those categories. The only way for a competitor to beat them is to come up from nothing to build a SNS and prove this naysayer argument wrong (and for its founders to have the stones to not get bought out). Until then, every FB post on HN is going to have people pointing to the FB network/userbase and saying "IMPOSSIBLE!"

It was impossible for Facebook once upon a time too... until it wasn't. Once upon a time Mark Zuckerberg was just an idiot with an idea, and here's where we ended up.
