What does Pb mean or stand for ?
The answer is of course lead....
Why do I know that ? well back in school I remember a dog eared poster that showed the Periodic Table - little did I know that this was my first brush with "Information Graphics" (as they were known then) - since then they have entered daily life more and more - from tube maps to weather charts and signposts to IKEA construction. According to Wikipedia, the first examples of infographics can be found on cave walls. They are visualizations of information or data with the purpose of bringing to light a point in a format that is graphically appealing. As our world moves towards a faster pace of life, the need to communicate a message quickly through visualisation is becoming more pronounced.
Over the last few years we have been overloaded with infographics with every company trying a new angle to get their place in sharing, distribution, communication, and marketing themselves - there are even websites dedicated to them to the point that I have become desensitised to them.
So I wearily clicked on a link entitled "How To Use Facebook To Market Your Brand - the description didn't disappoint using usual "infographic" flowery over the top speak "it lays out some of the more subtle aspects of the entire "like" dynamic. It lays bare the different species of fan, and concludes that each one should be approached with a slightly different pitch in mind" So I was not surprised that the first 5-6 points were pretty obvious re-hashed info but my patience was rewarded when I came to 2 elements at the bottom - the Fan Engagement Spectrum and Edge Rank.
The Fan Engagement Spectrum whilst v simple gives an interesting perspective on how a brand should view their fans from converted advocates to friends of "likers" - something that a brand should consider v carefully when planning FB and associated activity.
Edge Rank is something that i was vaguely aware of but I didn't know the formula which apparently takes into account how close you are with the original poster, how much the actual post gets liked, and the time since it was posted - check it out it is definitely worth a look - there is also a page dedicated to checking your own edge rank out.
