You, personally, are not. You, one of a cohort, kind of are.

If i run an e-commerce site, and see the vast majority of my users, but the minority of those that buy stuff, are on mobile and from India, maybe i need to optimise my site for mobile and lower-speed connections? Maybe something is wrong with my payment for specific currencies?

If i run a blog, ans the majority of my viewers come from France, maybe it's time i start writing localised content in French?

You get the gist.

You can see those things with just server logs.

[sofixa]

No, you can't. There's no way to get viewport from server logs, and presenting them a form digestible by marketing people isn't easy.

And for all of that, you need GA because...?

[sofixa]

Because it's easy and marketing people can work with it. Access logs don't have all the information ( e.g. viewport) and are cumbersome to parse.

I get the gist, you believe you’re so bad at running a shop and/or writing you can’t survive without creeping on people.

Also, look at both of your examples. They’re bad. They’re both best replied to with that diagram of holes on a WW2 airplane.
