There is one conversation that ranks as high on the discomfort meter as talking about strangers with your child. It is the discussion with your client about the ROI of a follower, a like, or a subscriber.
As much as any medium, social media plays "the numbers game" in an effort to bend perception. Let's not forget that the biggest fanboys and fangirls for social media are really marketing professionals and advertisers. They are the same people who learned to manipulate and exploit the tools before most average folks ever knew what a “Tweet” was. That being said, there is still skewed misunderstanding that numbers equal value or some type of discernible ROI.
Website designers, statisticians and advertisers alike should take a quick peek at the new Google Browser Size tool. It's nice as a quick reference tool to see where various parts of your website are falling at it comes to not simply usability, but user attention.
"This is useful for ensuring that important parts of a page's user interface are visible by a wide audience. On the example page that you see when you first visit this site, there is a "donate now" button which falls within the 80% contour, meaning that 20% of users cannot see this button when they first visit the page. 20% is a significant number; knowing this fact would encourage the designer to move the button much higher in the page so it can be seen without scrolling."
