Launched in March 2010, Pinterest is a relatively newcomer in the social media arena. This platform consists of digital bulletin boards where businesses can pin their content. Pinterest announced September 2015 that it had acquired 100 million users. Small businesses whose target audience is mostly made up of women should definitely invest in Pinterest as more than half of its visitors are women.
UK researchers used a dataset of more than 800 million Twitter messages to evaluate how collective mood changes over the course of 24 hours and across the seasons. The research team collected 800 million anonymous Tweets from 33,576 time points over four years, to examine anger and sadness and compare them with fatigue. The "research revealed strong circadian patterns for both positive and negative moods. The profiles of anger and fatigue were found remarkably stable across the seasons or between the weekdays/weekend." The "positive emotions and sadness showed more variability in response to these changing conditions and higher levels of interaction with the onset of sunlight exposure." 
Isabelle agrees. “Constant screen time damages your ability to see, and it also causes internal damage, such as anxiety.” Studies have shown that social media use can negatively affect mental wellbeing, and adolescents are particularly susceptible: one nationally representative survey of US 13- to 18-year-olds linked heavier social media use to depression and suicide, particularly in girls. And 41% of the Gen Z teens surveyed by Hill Holliday reported that social media made them feel anxious, sad or depressed.
Because large-scale collaborative co-creation is one of the main ways of forming information in the social network, the user generated content is sometimes viewed with skepticism; readers do not trust it as a reliable source of information. Aniket Kittur, Bongowon Suh, and Ed H. Chi took wikis under examination and indicated that, "One possibility is that distrust of wiki content is not due to the inherently mutable nature of the system but instead to the lack of available information for judging trustworthiness." To be more specific, the authors mention that reasons for distrusting collaborative systems with user-generated content, such as Wikipedia, include a lack of information regarding accuracy of contents, motives and expertise of editors, stability of content, coverage of topics and the absence of sources.
Social media has a range of uses in political processes and activities. Social media have been championed as allowing anyone with an Internet connection to become a content creator and empowering their users. The role of social media in democratizing media participation, which proponents herald as ushering in a new era of participatory democracy, with all users able to contribute news and comments, may fall short of the ideals. Online media audience members are largely passive consumers, while content creation is dominated by a small number of users who post comments and write new content.:78
If you use social media you need to engage with your customers, involve them in a dialogue, and ask them for their opinions. Post a picture of two items you are considering carrying in your store and ask customers which one they like best. This creates a dialogue which leads to shared posts which leads to engaged followers. Plus, if you follow this example, it will also lead to enhanced margins because your back and forth conversation will prevent you from buying the item that won't sell as well.
