Remember learning about “half-life” in high school Biology class?
A refresher: the time required for one half the atoms of a given amount of a radioactive substance to disintegrate.
Let’s apply this to social media: the half life of a Tweet is approximately 15 minutes – in other words, half of all people that will see your Tweet will see it in the first 15 minutes, and the other half might see it over the next couple hours. The half life of a Facebook or Instagram post is around 8 hours.
But the half life of a Pin? It’s between 3 and 4 months.
