In the few days since Facebook Connect launched, we’ve noticed something: blog commenting is becoming more authentic. The presence of trusted Facebook identity is creating a context for more meaningful conversation on the web.

For example, when Facebook Connect launched on Inside Facebook, Mark Zuckerberg, several people at Facebook, and dozens of people in the industry commented on Inside Facebook for the first time. Why? Because for the first time, Facebook Connect has enabled real identity on the web. In other words, everyone knows who’sactually talking.

What does that mean for online discussion?

1. If your comments are connected to your Facebook identity, you’re not going to publish things you might say anonymously.
2. Because comments connected to a Facebook identity are connected to a real person with a reputation (usually), they are more trustworthy (at least to the extent of that person’s reputation).

In other words, over time, Facebook Connect is going to slowly increase the authenticity and quality of conversation across the web. While this has been the goal of many identity systems for a long time, Facebook Connect has the potential to make it a reality more powerfully than ever before.

Rumors started to leak earlier today that Facebook co-founder Dustin Moskovitz  and colleague Justin Rosenstein were leaving to start their own company.

Facebook has since confirmed the rumor to us with a simple quote from Mark Zuckerberg: “Dustin has always had Facebook’s best interests at heart and will always be someone I turn to for advice.”

Fortunately, Rosenstein (who formerly worked at Google as product manager of Google Page Creator) has posted more information about their reasons for departure in a Facebook note to friends, which we have reproduced with his permission below.

In it, he describes briefly how Moskovitz and he plan to build to an “extensible enterprise productivity suite” that uses Facebook Connect as its user authentication system and borrows many of Facebook’s own design conventions. The two of them thought about building this suite from within Facebook but eventually decided that it would make more sense to build it within their own company. The choice quote: “We hope our products will become to your work life what Facebook.com is to your social life.”
