The differences between social media platforms
It is one of life's challenges - to explain the differences between the various social media platforms. Which one should you use to communicate certain messages? How differently do people interact with each platform?
There is no right answer; there are no rules which cover all eventualities.
However, I saw this quote in today's Guardian and I thought it provided a neat summary:
"If Twitter is a lively, rambunctious public salon and Facebook a warm gathering of friends and family, LinkedIn is a group of dead-eyed, sharp elbowed junior executives in the bar of an airport Novotel at 2am after a conference, slapping themselves on the back, while scanning their peers for signs of weakness."
Ok, it may be a bit of a cynical view about LinkedIn, but I do think the Twitter / Facebook comparison is a good one.
The other point I enjoyed is "Thou shalt chill out a bit with the goddamn #hashtags." They used to help in searching for topics but they are no longer required. If you must use a #hashtag, then please use them sparingly.
