I'll just copy-paste my response from the other rushing thread:
I'm indifferent, but rushing is a legitimate strategy, even though it's kinda annoying. However, if you're a good player, you can counter it, and it's very funny and exciting to witness it in a pro-match, like Jaedong doing a 4-pool Zergling rush against Flash (in Starcraft, if you're wondering), it was awesome.
Explanation of the 4-Pool Zergling Rush:
In Starcraft Skirmish matches you start with 4 of your workers (Drones, SCVs or Probes) and your main building (Hatchery, Command Center or Nexus), ordinarily players gather minerals and build workers, the amount of workers depending on the strategy you want to be using during the match.
Normally Zerg spawn 9 or 10 Drones before building their next building, which is ordinarily either a Spawning Pool, or a second Hatchery. The Terran build 10 SCVs and while the 11th SCV is building they build either a Supply Depot, or a Barracks. The Protoss usually build 10 Probes, then a Pylon and then either a Gateway, or a Forge if they're looking to Fast Expand.
Now to the topic at hand the 4-Pool Zerg rush. A normal Zerg rush is a 9-pool rush, which means spawning 9 Drones, then building a Spawning Pool and then spawning the Zerglings. A 4-Pool is more crazy because you don't spawn any Drones, you just gather minerals with the Drones you have at the start, until you gather 200 Minerals and build your Spawning Pool. This is my favourite kind of rush because it's very rarely used today, and it's very interesting to see someone use it.
tl;dr: I like rushes because they're very fun to witness when utilized properly, and it's fun to see the victim struggling to counter.
