But... but... we paid money! Notch owes
us! *whine whine whine*
Yeah, I've seen that, too. Pretty much why I stay out of the general discussion threads on the Minecraft forums. I go there for texture packs and build ideas and the occasional mod, and that's it. The actual Minecraft community is a bunch of fucking crybabies.
My main gripe is that every major update introduces a fuckload of bugs. I would rather they be delayed so bugs can be fixed. Maybe that's what this pre-release was all about? If so, I am totally in favor of them doing pre-releases going forward, so those of us who want to wait for a "production" release can have more assurances that it's not a buggy disaster.
