The first and last time I clicked an ad was roughly 20 years ago. I was a child, playing RuneScape and orgazing a clan, and I wanted to post our clan events on a website.
An ad for one.com (a web host, called b-one back then) was shown above the RuneScape client. I thought about it and decided to click it. I landed on the website and made an account, played around a bit, and asked my mom if she'd pay for it. In that moment, not only did I become a paying customer, I became a web developer. The latter of which I still am to this day.
Being exposed to such life-altering artifacts on the daily seems like a terrible idea, so I've blocked ads ever since.
I love Organic Maps. I used it quite a lot for navigation across Europe and here's my list of findings in order from good to bad
Now, if it wasn't for this last point, I'd use it over Google Maps every time. But the battery consumption is so bad that I only use it if I know that I can reliably charge my phone throughout the trip.
