Facebook announced several big developments last week at the f8 conference in San Francisco, California and the Inside Network was there to bring you breaking and in-depth coverage of the event.

Check out our detailed analysis of the Open Graph’s new social plugins and API, below, along with news from conference sessions and related stories. For those who followed during the day, note that we’ve since been providing follow-up coverage on specific topics that came out of the conference, like our story on how to administer off-Facebook pages via the API from earlier today.

But first, an update to from Facebook. The plugins have made it to more than 50,000 websites in the week since they were launched, the company announced in a blog post yesterday.

Facebook launched the plugins with 75 partners — big names like CNN and Levi’s – but the other 50,000 sites have implemented the changes on their own. Company founder Mark Zuckerberg predicted the Like button plugin, in particular, could get a billion impressions in the first 24 hours after launch. It did.
