When I originally saw this posting linked from on another site, I reached out to the author with a constructive comment that he work with other people. Now the comments are not visible.
So is the author wallowing in pity or depression?
As a long time coder, most of my work is no longer in use. Many of my current internal projects at work are only in use by me or a small group of people, enough though they could help hundreds of others (clients, coworkers).
And code is never done. I have dozens of projects in various states of completeness. Even the code in production isn't "truly finished", but it works well enough and has passed review.
I'm going to work on a few other OSS projects that may never be seen by a handful of folks. That's fine. I don't want fame, I like solving problems and helping others.
