I am all for experimentation and creating something new. But so many of these projects out there are not forks of current projects, they are complete rewrites. Is this because the new project is vastly different? Nope! That is the issue, they aren't extremely different.

The reason this is a problem is because web tech is constantly changing, to the point that so many of these projects end up in the scrap heap far faster than other tech. It causes problems with long term service due to compatibility issues with ever changing dependencies.
