...forgive me while I pick a proverbial bone, not with you, but with the nature of social media in general and perhaps even with our beloved G+ in particular, which is that in your article you mention a variety of topics well suited to social media, such as sports, music, business, technology of course, and blogging, which is a very specific type of writing. However, as a writer, I will not give up my own website as a creative vehicle because social media has yet to get hip to the enormous artistic community that is signing on, which now mimics the time when musicians started leaving the major music labels to pursue a more independent voice online.
Google+ has provided many valuable tools for artistic media that lend themselves to powerful visuals and graphics - you can insert a video, a photo album, or a hyperlink into a post, therefore immediately capturing the attention of the global cultural audience about which you originally inquired. Yet although it is words
themselves that drive all of this, writers have not been presented with the tools that assist their own trade, not even some of the basic ones provided in WordPress, for instance. The basic assumptions are that the most popular topics are marketing, technology, brand-building and business, and that if writing is mentioned it is mentioned in the form of "blogging." Another assumption is that social media is becoming predominately visual. It is not. There are different sorts of people: those attracted primarily to visuals, those attracted primarily to the written word and those attracted to both. But social media distinctly assists the visual more than the written expression.
There are scores of poets, memoirists, essayists and writers of every ilk who are turning to social media to promote their work, as have musicians before them. Our fragile and unstable world economy has produced a shortage of jobs, a situation that always compels the creatively inclined to produce artistically. This community is increasingly turning to social media to find an audience.
You wrote: People care about this new globalism whether it arrives at their desk through sport or business or fashion or food,
and you are absolutely right.
Yet what is almost always left out of that list are the arts, which themselves should be considered a vital part of this global social media conversation, along with any meaningful conversation about technology, branding and business.
