FYI - this is bogus advice, if they really meant that smack packs don't ever require starters... The beer you brewed is right on the outside of the OG range for pulling off with a single smack pack and no starter - but brew something with any higher OG, and you definitely will need a starter (or multiple smack packs).
Before you do any bigger beers, do some searches here for starters, and play with the starter calculator at Mr Malty.
EDIT: That came across a bit strong - you'd definitely WANT a starter for a bigger beer. You can surely ferment one without it, but you'll be happier with the end product!
