I prefer the unique challenges of hundreds of thousands or millions of lines of code and a user base getting real work done with a system to the repetitive tasks of greenfield development ("oh joy, time to implement password reset again!").
PS If anyone is sitting on this type of challenge I've got my email in my profile, I am looking for some freelancing hours.
I hope in the future people feel free to post job postings or freelance projects in this subreddit.
It's a very good book and more people should read it. Some great insights on how to get control of an existing system.
There's a lot of projects out there that need to be kept alive. The objective is to make them fun to develop again.
