A few fun charts:
As most of you know we focus on plain vanilla public betas (77.7%). But we also collect sites in alpha (4.9%), sites which have not publicly launched yet (private alphas, private betas, sites in stealth mode, …) and require some sort of invitation to get in (15.7%), or sites which come in some other beta-ish (gamma, zeta, feta, …) flavor (1.7%).
Google has launched only 2.6% of all betas,
but they still lead the pack compared to Yahoo, Microsoft and others.
