Language is important and 'portfolio career' was supposed to be the new watchword for post-austerity employment.
Instead of relying on a nine-to-five job for 40 years before collecting a pension and gold watch, we were going to become mini-entrepreneurs, holding down a variety of gigs.
So the part-time secretary teaches yoga in the evening; the shop worker on 16 hours minds kids in the afternoon. Essentially, it was women, of course, who embraced the notion - turning a hobby into payment, a cottage industry into a job.
And for some, Airbnb - the scheme that puts your spare room to good use - proved immensely popular.
Our Irish predilection for living in a three-bed semi, even if it's largely unoccupied, put us ahead of our European apartment-loving tightly fit neighbours.
Sadly, our concept of 'making a few bob on the side' doesn't quite match the language of the tax code. Some hosts didn't see it as anything that should concern the boffins at tax collection, who are surely encumbered with weightier matters like finding tax-avoidance measures for American multi-national companies.
But Revenue could certainly have made things clearer for those in receipt of this transient income, especially as many are PAYE workers unaccustomed to handling their own tax affair.
Revenue itself often fudges and obscures its own language so as to leave itself open to 'revision' later on, so that picking one's way through the maze becomes a trudge through muddy waters.
It offers a tax-relief scheme called Rent-a-Room to alleviate the chronic shortage of rental accommodation, allowing you to earn €12,000 a year tax-free for letting a room.
Not unreasonably, many people thought that was exactly what they were doing with Airbnb.
Many correctly realised that as far as the tax authorities are concerned, income is income, irrespective of its source, and that in hosting an Airbnb room you're treated in exactly the same way as a guesthouse owner or someone with a second income filling envelopes or cleaning houses.
Revenue has now compelled Airbnb to hand over all the details of those people in order to back-tax them. Many will choose not to bother hosting any more as a result; others will be left with an unexpected bill.
But some may just up the ante and create a commercial product and simply charge more.
All however, move away from the purpose and joy of the Airbnb model, which is a shame.
