The development of social media started off with simple platforms such as[20] Unlike instant messaging clients, such as ICQ and AOL's AIM, or chat clients like IRC, iChat or Chat Television, was the first online business that was created for real people, using their real names. The first social networks were short-lived, however, because their users lost interest. The Social Network Revolution has led to the rise of the networking sites. Research[21] shows that the audience spends 22% of their time on social networks, thus proving how popular social media platforms have become. This increase is because of the widespread daily use of smartphones.[22] Social media are used to document memories, learn about and explore things, advertise oneself and form friendships as well as the growth of ideas from the creation of blogs, podcasts, videos and gaming sites.[23] Networked individuals create, edit, and manage content in collaboration with other networked individuals. This way they contribute in expanding knowledge. Wikis are examples of collaborative content creation.
Great list and please don’t get me wrong here, I am sick to death of Facebook. Is there another alternative TO Facebook? Put simply, NO!!! The other social media sites are devoid of the basic common denominator, Collaboration!! While they MIGHT get you a closed network or a specific audience, it doesn’t cater for interaction with all of the platform. What we really need is somewhere that has a home page with your posts that is broadcast to ALL other users or chosen crowds. We need a news feed to cast all of the posts for people to interact with. Twitter, Snapchat, Google+ and Instagram etc etc, just don’t cut the mustard as far as this goes. Some of the others mentioned are specific to specific audiences and are nothing like Facebook. That is why all other alternatives fail dismally!! I wish I had the money and development time to produce it, but alas I don’t.
Pinterest is a social curation website for sharing and categorizing images found online. Pinterest requires brief descriptions but the main focus of the site is visual. Clicking on an image will take you to the original source, so, for example, if you click on a picture of a pair of shoes, you might be taken to a site where you can purchase them. An image of blueberry pancakes might take you to the recipe; a picture of a whimsical birdhouse might take you to the instructions.

Social media "mining" is a type of data mining, a technique of analyzing data to detect patterns. Social media mining is a process of representing, analyzing, and extracting actionable patterns from data collected from people's activities on social media. Google mines data in many ways including using an algorithm in Gmail to analyze information in emails. This use of information will then affect the type of advertisements shown to the user when they use Gmail. Facebook has partnered with many data mining companies such as Datalogix and BlueKai to use customer information for targeted advertising.[49] Ethical questions of the extent to which a company should be able to utilize a user's information have been called "big data".[49] Users tend to click through Terms of Use agreements when signing up on social media platforms, and they do not know how their information will be used by companies. This leads to questions of privacy and surveillance when user data is recorded. Some social media outlets have added capture time and Geotagging that helps provide information about the context of the data as well as making their data more accurate.
In the early days of social marketing, there was little competition for the dollar—not so today. For example, you can spend thousands of dollars on a Facebook ad campaign and, sometimes, get no return on your investment. By its very nature, social media is a short attention span media—it is much harder to get someone's attention with a Tweet then it was to get someone's attention with a newspaper ad. That's because ad headlines and copy are harder to write on Twitter or Instagram.  
If anything, social media is probably about to move more toward ephemeral sharing for quicker, more intimate sharing without the stress of having to blast something out to hundreds or thousands of followers that stays up there unless it's manually deleted. The pressure of garnering tons of likes and comments on regular social media posts also plays a huge factor, suggesting that more casual forms of social sharing, such as through stories, could be the way of the future.
Publishing content has become exponentially simpler over the last several years, which has helped skyrocket the use of social media. Non-technical web users are now able to easily create content on a rapidly growing number of platforms, including those that are owned (hosted communities, blogs, etc.), rented (social networks or third-party communities), and occupied (commenting, contributing, etc.). Today's web has shifted from a "one-to-many" to a "many-to-many" method of engagement, and we're loving it.
Users typically access social media services via web-based technologies on desktops and laptops, or download services that offer social media functionality to their mobile devices (e.g., smartphones and tablets). As users engage with these electronic services, they create highly interactive platforms through which individuals, communities, and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online.
