I recently blogged on my company's website about becoming the maintainer of the Views iCal module in Drupal. It's been a great experience, and as a Drupal developer, I see a strong need for other people to take up the maintainer role of many modules in Drupal. There seems to be a whole generation of developers that were really active in Drupal 6 and 7 that have become less active. But that's OK, people move on. Now with Drupal 8, we have a pressing need to continue the work of porting modules to Drupal 8 and working towards not just dev or alpha versions, but full releases.
The Drupal community is strong, and if I had one thing to say to people, if you have doubts about volunteering to become a maintainer of a neglected module, don't! Don't let impostor syndrome get to you, being a maintainer is actually a great way to learn Drupal. Sure, it can be a lot of work, but seeing other people benefit from your module is a rewarding experience.
