Why I bother
Keeping the big end of town honest.
I grew up before the internet and learnt it as it arrived, so I remember what finding anything used to take. I've also spent years around real developers, so I know what software used to cost to build.
Big companies charged a fortune for things that weren't special, because they could and because you had no way of knowing. Now you do. You can build the thing you actually want, without the feature bloat, for close to nothing.
To be fair to them, some of what you're paying for is reliability, and that's worth real money. You just deserve to know which one you're buying.
Know enough to not get played.
One of the five Do moves, and the whole point of this page. I can't stand watching people get taken advantage of because nobody told them there was another way. I wrote a whole talk about it called Every Town Needs a Batman.
