As Google+ moves towards even greater integration with other aspects of the web - as they have already done with their foray into local search - its growth may skyrocket, both in terms of business and personal use. For information on how to start using Google+, read "Getting started with Google+"
Image-based networks will record huge success
There has been a consistent trend in 2013 toward sharing through image and video, rather than text-based content. Visual content will increasingly become a critical piece of any solid content strategy, and social networking site. Pinterest would lose its reputation as a 'women's only' network and become an integral part of retailers' marketing strategies.
Other image-based social media sites like Instagram, Slideshare, Tumblr, Path, and Mobli will continue to grow, and businesses will need to become more mindful of the 'sharability' factor of photos on their websites and blogs in order to derive significant benefit from their social media content marketing efforts.
Video-based social media (the rise of micro-video)
It seems as if writing 140 characters and taking three minute long videos is becoming too tedious for many internet users. Micro video to the rescue!
With the emergence of micro video apps like Twitter's Vine and now Instagram's video sharing feature, there is more movement toward real-time video sharing. And not just any videos; with Instagram allowing 3-15 seconds per video, and Vine allowing precisely six seconds, users are even more likely to create and share videos from their smartphones.
It would be interesting to see if and how these bite-sized pieces of content would change the playing field when it comes to video-based social media.
With their radical makeover and re-branding efforts earlier this year, MySpace appears to be getting its second wind. Offering an iPhone app that allows users to network, receive private messages, and listen to their own personalised radio station, MySpace seems on track for growth in 2014.
MySpace may never again compete in the same space as Facebook or Twitter, but it would be interesting to see how the network grows among bands and music-lovers.
