They actually joke about their "beta's" on one of their hidden sites.
11. When will you take Google Gulp out of beta?
Man, if you pressure us, you just drive us away. We'll commit when we're ready, okay? Besides, what's so great about taking things out of beta? It ruins all the romance, the challenge, the possibilities, the right to explore. Carpe diem, ya know? Maybe we're jaded, but we've seen all these other companies leap headlong into 1.0, thinking their product is exactly what they've been dreaming of all their lives, that everything is perfect and hunky-dory – and the next thing you know some vanilla copycat release from Redmond is kicking their butt, the Board is holding emergency meetings and the CEO is on CNBC blathering sweatily about "a new direction" and "getting back to basics." No thanks, man. We like our freedom.
