By most measures, both for ad platforms and advertisers (and subsequently users), audience-targeted ads outperform context-targeted ads. You could go back to a world of only context-targeted ads, but publishers would need to make their business models work with lower RPMs, advertisers with lower ROAS, and users with less relevant ads (to them).
How many pageviews are you doing per month and what is your Google Adsense RPM? Before throwing advertising out, wondering if the ads are working as effectively as they should.
In addition, agree with keiferski that ebooks could be a good path forward.
You could also do classes or "bootcamps" for skills training.
What are some of the top tech companies? I have to imagine the normal ones like Google, Facebook, and Amazon. But then more local companies would be UOL, Itau, Banco do Brasil, Bradesco, etc?
The taxes you're referring to, I presumed, are things like DMV fees. Those are used for things like roads (construction, repair, salting, plowing, etc), bridges, highway patrols, etc. They aren't market rate because they don't actually cover their stated purpose, thus are subsidized from other taxes. Additionally, they don't price in externalities like noise, pollution, emergency services due to accidents, death and injury to persons, etc.
The scooters are indeed left on sidewalks. Luckily the 20 pound scooters aren't actually killing or maiming people, spouting out toxins into the air, ripping up the asphalt, blaring "honk" noises at all hours of the day, etc. Not much of a public nuisance all things considered :)
Also, visit any of the neighborhoods on the western half of San Francisco and you'll discover that it's de facto not allowed to be handicapped or pushing a stroller due to cars owning the sidewalks.
1) Clean up the plural duplicates, e.g. peanut/peanuts, leek/leeks, carrot/carrots, etc.
2) I've never considered the author, is that common?
3) Mode to toggle pictures on would help scanning, cooking is very visual
4) Not simple to design, but some way to have either/or ingredients (e.g. peanuts OR cashews) could be useful
