To each their own but ideally so that you don’t have to drive everywhere. So that meeting your neighbors isn’t so rare, and you can build community trust. So that you don’t have to buy everything in big huge amounts so you don’t have to make a big trip. So that the young and the elderly can get around without assistance or endangering others. So that common areas can grow and give your community a unique identity.
Basically less cars/road infrastructure and building community trust. Though, and you’ll probably mention it, it would take way more than a walkable neighborhood to fix these things. I mean if you don’t even want to know your neighbors this would be hell for you. While I appreciate the idea of communal spaces, there is a lot to be said for independent space as well.
There are a lot of reasons in here about how bad reviews kill products, but I didn’t see mentioned how exceptional a product has to be to garner GOOD reviews. A business will get to the point of almost harassing you to leave a good review. In my experience people leave reviews when they are unhappy, and say nothing when they are satisfied.
An example of this was Teenage Engineering K.O. II EP-133 sampler. A bunch got released with broken fader knobs and the wave of bad reviews and complaints flooded in, drowning out the actual pros and cons of the device. T.E. isn’t exactly floundering from it, but in another circumstance that could have killed the product (which I find to be phenomenal).
