The world of social media is a fast-paced environment, one that changes from day to day. To help you keep your finger directly on the pulse of what’s happening in social, we’ll be putting together a weekly roundup of all the latest social media news from around the web.

Don’t Be A Square

Somewhat out of the blue, Instagram has announced that images posted to its social media network no longer need to be square. Of course, square images are still welcomed, but rectangles have joined the party.

‘It turns out that nearly one in five photos or videos people post aren’t in the square format… friends get cut out of group shots, the subject of your video feels cramped and you can’t capture the Golden Gate Bridge from end to end.’

As mentioned by Instagram, this is an especially positive change for videos, which are now able to capture a far wider scene, making them “more cinematic than ever”…

Call me ‘M’

Facebook M

Following, sort of, in the footsteps of Apple and Microsoft, Facebook has announced that it is to begin testing a new service called ‘M’.

Sitting inside Facebook Messenger, M is a ‘digital assistant’ (AI) digitally trained to ‘complete tasks on your behalf’. Though currently in its early stages, the scope of uses for M is impressive:

‘It can purchase items, get gifts delivered to your loved ones, book restaurants, travel arrangements, appointments and way more.’

1 Billion Users Per Day

Yes, you read that right. It’s no typo. Mark Zuckerbeg, founder of Facebook, has announced that the social media network reached, for the first time ever, 1 billion users in a 24 hours.

In a post to his facebook page on Monday, Zuckerberg announced that “1 in 7 people on Earth used Facebook to connect with their friends and family” that day.

That’s an incredibly impressive figure, and even more so when you consider than Facebook “only” managed to achieve a total of 1 billion users in October 2012.

Slideshare Finally Being Linked In

It’s been over 3 years since SlideShare was acquired by LinkedIn, but after a long road it has been announced that Slideshare will, from now, be known as LinkedIn SlideShare.

Now, you may not think that too exciting, but it comes with a new feature; clipping. In a similar way to Pinterest, users can now use LinkedIn SlideShare to clip – not pin – interesting professional or personal articles to clipboards.
