There is no reason to make spore crawlers, because unlike banshees, which harass drones, overlords don't actually need to be anywhere. He can easily pump out 2 more queens, which build very rapidly, then use them to spread creep afterwards, so they aren't wasted (or use them at his next expansion and the extra in-base hatch he will need for 2 base muta/ling). The point is, viking harass dropped off during beta because it was too easy to defend. Unlike with Phoenix, if you have a hard time dealing with his viking harass, you can actually build mutas to counter them (the correct counter would of course be hydras, but you can use your mutas to harass him as well).
