Some Facebook profiles and pages were down for a while this morning. Downrightnow.com, a site created to tell you when popular web services are experiencing trouble, reported a widespread service disruption, likely from a server issue.

Facebook acknowledged in a statement that it "experienced an issue" that prevented some people from loading Timeline or Pages content for a "brief period" — several hours, by most estimates. The issue seems to be resolved now.

Meanwhile, in other social media news ...

Twitter is Public

Yesterday we reported about Twitter's IPO. The stock hit $47 in early trading, up $21 on the opening price. What will this mean for Twitter? No one really knows. But suffice to say the Twitter IPO was much smoother than Facebook's 2012 IPO.

However, more attention is being paid to how Twitter really works. In an article from Businessweek, Paul Ford took a closer look at The Hidden Technology That Makes Twitter Huge. Ford wrote: 

How do you look inside a tweet? It’s easy; the structure of a tweet is a matter of public record. Twitter, as a modern Web company, reveals to the world some of the technology it uses, in the form of an application programming interface — an API — which allows external software developers to build tools on top of the service, making it more widely used and thus more valuable for everyone.

When you really stop to think about it, what goes into broadcasting 140 characters is pretty darn impressive. To the misinformed, Twitter may seem frivolous. But to those of us who appreciate the anatomy of complex systems, a tweet is, as Ford noted,  " ... the manifestation of the human desire to communicate with many other humans at once — to exercise some influence, to inform, amuse, or outrage."

Facebook Reinvents the Like

This week, Facebook introduced a new like button that is designed to help people share more content across the web. In a darker shade of blue, the new like/share button hopes to make it easier for users to both like and share content online. Like lets people post links to Facebook with one click, while Share allows them to add a personalized message and customize their target audiences before posting.

According to Facebook, if you're currently using the old Like button, you'll be automatically upgraded to the new design as part of the roll out.

YouTube Connects Google+ 

The YouTube development team has integrated YouTube's commenting system with the Google+ social network. What does this mean?

YouTube claims it's an attempt to move more relevant, high-level comments to the top of the feed while pushing less helpful comments down the page. But it  also means that you need to have a Google+ account and log into it just to leave a comment on a YouTube video.

Although many people have probably already connected their YouTube accounts to their G+ pages, the change is drawing plenty of complaints. In fact, Change.org, a site that enables anyone to start a petition, said 10 petitions with a total of more than 60,000 signatures were launched in the day since Google+ was integrated into YouTube comments. All but one lone petition with 10 signatures want YouTube to reverse the change.

By encouraging (ahem, requiring) more people to sign in through G+, YouTube hopes to discourage users from leaving negative comments. Using the G+ account means the user's account name will show up alongside the comment.
