Friday at last! As we close out another busy week, the SM& digital team has an update on all the social media news you may have missed.

Like-bait no more: Facebook has yet again made changes to the algorithm that filters out what users see in their newsfeed. One significant change for brand pages? Facebook will penalize users for “like-bait” content, such as images asking users to “LIKE” or “COMMENT” to display a preference. What was once a go-to means for generating engagement will now do the opposite. The bottom line for social media managers? Facebook wants to become a news source—be sure to share timely, relevant content to show up in your followers’ feeds.

The not-so-friendly skies: It was a bad week for airlines on social media. From bomb threats to graphic images shared on a corporate account, the industry faced quite a bit of turbulence. Perhaps the biggest surprise of all? US Airways says it won’t fire the person responsible for sharing a pornographic image on its Twitter handle. As SM&’s Director of Digital Communications Tweeted this week, we’d fire ourselves and flee the country after a gaffe of that magnitude.

LinkedIn goes mobile, again: This time, LinkedIn has made SlideShare a mobile app for its users. Now you can pull up that great slideshow one of your connections shared while at a meeting or on the road. As mobile use of LinkedIn climbs, expect to see the professional social network invest in even more apps.

Twitter offers more ads, again: Fresh off the news it’s debuting 15 new ad styles, Twitter users are now seeing promoted tweets for other apps while mobile, allowing them to download an app like Spotify without having to remember to click to the app store later. It’s a nice change—can’t wait to see what Twitter rolls out next.

General Mills adds some serious fine print: Could liking a company’s Facebook page mean you give up the right to sue the company? General Mills thinks so, and recently added language to its website that tells users by joining one of its online communities, they’ve ceded the right to sue.  Expect big brands to follow the inevitable legal wrangling about agreements like this closely—we know we will.
