Some mornings you wake up and there's a smell in the air. It's not instantly noticeable, but you can tell. Something is different. Something that was true the night before, as you lay in bed, eyes red from exhaustion, is no longer true. This morning, I was woken up by my wife, "Daddy Cool! Daddy Cool!" (Which is her nickname for me - I wore a lot of hats in my 20s) "Daddy Cool, wake up! You've got to see this"

I lurched out from under the quilt, rubbing my eyes. "What is it?"

"It's Facebook. They've done it. They've finally done it?"

"Done what, woman? You're being hysterical!"

"They've implemented a hashtag functionality. At first it's not really going to have much impact on the user experience, aside from the tags being clickable, but it's only a matter of time before they start showing up in Facebook search results, and then the possibilities for advertisers and data gatherers are limitless!"

I gazed grimly at the grey and troubled skies outside the bedroom window. The garden was completely over run by bluebirds, all staring directly at me. Silent. Judging.

It had begun.
