GP may have meant "great" in terms of support; that's one of the most often-cited benefits of Linode over other providers. They appear to give a crap about their customers and are very responsive over several open communication channels (forums, IRC, etc.). That may or may not scale if they were to someday have 100x the customers.
For example, 10 VPSs per physical server, no more. If we're going to up 1000 new VPS, we're going to need 100 new physical servers.
