This kind of reply isn't really that constructive, the guy raised some fair points... A lot of smaller companies and startups seem to do incredibly well with not even 10 employees, let alone 50. I understand there's more to running a company than meets the eye, but I really do wonder if all 50 people spend their days at vine being productive.
Please name a company of 10 people that manages a user base in the tens of millions with similar technical requirements as Vine (bandwidth, storage, etc). If such a company exists I believe it would be an outlier.
