You know what hasn't been done? A blog post about how to make a service that fulfills the needs of most people most of the time.

All of the online and print material about such things focus on how to achieve massive scale correctly. Don't get me wrong; this is valuable and, generally, sound advice.

However, it also ignores the majority of use cases for software.

I would love to see a blog post here from someone who has solved a very specific problem for a very small audience, and gotten a very enthusiastic response. That would be meaningful on a larger scale for me.
