Google didn't invent online advertising you know. Adwords is a fairly terrible platform and is best suited to tiny shops. I'll never understand why El Reg uses it as there are most certainly plenty of options out there.
Regardless, everybody pays some extra for things they'll never own or even know exist. That's what currency is really for & why it's most difficult to trade previous metals, gemstones and livestock for houses and whores anymore.
If you own anything containing titanium, any footwear with Vibram soles, have a saddle with interchangeable composite gussets, own a precision target rifle manufactured after 2004, ride or live in a country that used trains with wire wheels, have anything containing materials developed with research done with particle accelerators (the safety glass in your car, CD's, some labware and drinking vessels), some brands of submersible camera enclosures, seat belts, eat honey or products containing honey, enjoy those chocolate candies with unique melting properties that have an upside down 'W' on them, or own a building with a blast door, or scads of other common stuff you're paying a little premium to me to cover the costs of the equipment I've built for those companies or the companies who provide things to those companies. Neat huh?
I created a name for these systems, but apparently some asshole named 'History of Civilization' already had 'economy' registered. Fucking USPTO right? Those guys are just so unorganized. Maybe I should just refile. It's a lot easier to do that these days you know. I pay a small fee to connect a phone designed and made with parts made by employees in dozens of countries to access a network run on equipment made by lots of different people that's used by software created by lots of other people to fine a trademark application that's dealt with by an entire agency made up of equipment and people. My first patents and trademarks had to be done with actual paper! The supply/process chain was a bit different, the paper was made in this country, but that's about all.
I had no idea all those people went to work everyday, for free. But now that you've clued me in I know I don't have to pay for anything because those people are all so generous they'll work for free, just out of the kindness of their hearts. I bet they're all Canadian. That's just a nice lot, those Canadians.
