Post-it conversations are the new craze that could be taking over your office block

BORED workers in a towering office block have started a trend that could be coming to your building. Check out what they have to say.

WHO said time at work wasn’t being used productively?

Post-its have become the latest accessory in a craze taking over San Francisco, sparked by a friendly war between two office blocks.

The trend was re-ignited last week when two buildings had a conversation complete with a game of hangman, pictures of Pac Man and confessions of “we r hungover” SFgate blog reports.

It’s been dubbed the city’s “newest social media platform” by a dedicated Tumblr and could be coming to a building near you.

Here’s how it went down:
