Happy Friday, social media aficionados! As we wind down another productive week, it’s time to take a look at what happened this week in the digital communications world. As always, weigh in in the comments if you have a tip or trend you’d like to share!

New Twitter profiles are now available: People really like the new Twitter profile design. The network has made the new, visual-heavy profile available to all users ahead of its initial schedule. Aside from the visual differences, the new profile allows users to “pin” a message to the top of their profile, much like Facebook. It also makes a user’s more popular Tweets display slightly larger.

Will Tweet for Work? Mashable reports that with its new redesign, Twitter has become a prime place for headhunters and potential employers to fill jobs. You can now pin some of your best work to the top of your profile, and a user’s more popular Tweets will be more prominent than those that don’t receive much interaction. But tread carefully: if your content is controversial or offensive, your new profile may actually squelch potential opportunities.

In this edition of #hashtagsgonewrong…:  It sounded like a great idea: Encourage the followers of the New York Police Department’s Twitter account to share pictures of themselves with members of the NYPD by using the hashtag #myNYPD. It started out well, but eventually users overran the hashtag with unflattering pictures of the department. The takeaway for your organization? Thoroughly think through all the possible outcomes of your campaign before you launch.

There’s an app install ad for that: Google has followed the lead of Facebook and Twitter, allowing app developers to advertise in a way that allows users to directly download an app through YouTube.

1 Billion Served by Facebook Mobile: We still believe the death of Facebook has been greatly exaggerated. Need proof? More than 1 billion users logged onto their Facebook account from a mobile device in the first three months of 2014.

Trouble in Mountain View? On Thursday, Vic Gundotra, executive in charge of Google+, announced his resignation after eight years with the company. Speculation is that the digital giant may be wavering in its commitment to its social network, but there’s nothing official yet. So keep on expanding those circles—there’s a massive potential audience on G+. (Need help navigating the service? Our Director of Digital Communication can help.)

Instagram gets personal: Sick of seeing selfies? Instagram has tweaked the algorithm on its “Explore” function, meaning you’ll see pictures that people you follow have liked or commented on. So, unless you’re a regular #selfiesaturday participant or follow someone who is, you’ll likely see more relevant content on that tab soon.

Extra, Extra! Read all about it (on Newswire): Facebook and Twitter continue to merge into one homogenous social media beast. This time, Facebook has launched a service called Newswire in partnership with Storyful. It’s intended to be a breaking news source for journalists, although it’s publicly accessible to all Facebook users. Clearly, Facebook is sick of seeing collections of Tweets on major news websites when news breaks. Will it work? Some journalists are skeptical, but Facebook is a behemoth and these sources are vetted, unlike many Twitter accounts. PR pros should keep an eye on the service.
