Speaking at the local meetup is really a good way to improve your skills. At the same time, attending a meetup and joining others is also one of the ways to keep yourself up to date with the community.
July 2017, I attended DC Scrum User Group meetup for the topic Neuro-Leadership. What an informative session we had, I must say.
If you are looking for session information, you can find that at below link.

Enjoyed being part of the community.
