One of the enjoyable aspects of this practice, was during the selection process for "what software do we want to use?". I didn't have to select only open source projects which were "almost a perfect fit, with XYZ problems we can live with". Instead, I got to select software with (to me) better criteria:
* what are the upstream devs like to work with?
* what is the future of this project?
* is this project something we would be proud of our association with?
* working on this project, will myself or my team be exposed to new skills and technology?
