Thanks for your feedback. I know what you mean. VersionEye has already a pretty good GitHub integration. Currently we are working on automated change logs. And I want to work together with TravisCI and CodeShip to run tests against newest versions. I think together with automated testing it can be very valuable.
I maintain a couple open source projects by myself. And I don't release new versions just for fun. Releasing a new version is a lot of work. If I do it than there is always a very good reason for it. For example BugFixes, SecurityFixes, New Features or Speed & Memory Optimisation. And I think if somebody else is releasing a new version of an open source project he has the same reasons. And that are all good reasons for me to update. That's why I started VersionEye.
