Why 2020 Is A Critical Global Tipping Point For Social Media

This year is likely the last one ever in which you can say that more than half the planet is not on social media.

Hootsuite just released a massive digital state of the union report. Some of the high-level findings:

5.2 billion of us now have phones globally
4.5 billion are connected to the internet
3.8 billion are active social media users

That 3.8 billion is 49% of the planet’s population, and it grew 9% over the past year.

You can now create RSS feeds based on keywords with Ping.it

Imagine how useful it would be if you could set up a Google Alert for a keyword but only be notified if that word or phrase were mentioned in a news story that had more than 50 shares on social media. And would you find it even more useful if you were notified not by email but within an RSS reader?

Consider a tool that could tell you when a news story mentioning a particular word had more than 500 Facebook likes or 100 Twitter shares.

New functionality in free tool Ping.it does just that. And it lets you to determine the number of shares, Facebook likes, Twitter mentions or comments a story has before it is flagged up.
