Although I agree with many points of the article, let's review YCombinator funded projects and we'll see they are no joke.

It all depends on the needs of the project.

The promotion that some projects may get from being in an accelerator can be enough for some. For other it will be the little or big seed money they receive. Other will learn things that wouldn't have learnt otherwise.

And for the majority, as it always happen in business, it will be useless even if they happen to have the best mentors.

This.

Nothing will replace my Synology and the amount of services it gives me.

I already have two that backup each other. Best purchase of the year :)

I love minimalism, but I see having self-control as a better option than spending 500$ in a device you are not going to allow yourself to use.
