You don’t need an invitation anymore to check out Google+, the search giant’s stab at social networking. Earlier this week, Google (Nasdaq: GOOG) opened it up to the public, although–as it does with almost all of its projects–the company said it would continue to evolve the platform, thus the Beta tag. You also don’t need an invite to check out what I think is its best feature: Hangouts, the group video chat that lets you connect with up to 10 people at a time. (FierceEnterprise)
