Adarsh,
I'd be interested in doing the beginners talk. I would structure it in two parts:
2. Conceptualizing Vim as a tool which evolves with you and the importance of owning your vimrc. If you are a developer, you like automating systems and evolving your vimrc is a great way to help automate your workflow (which is, after all, a system).
These were the two "ah-ha!" moments that solidified my love for Vim.
I am not an experienced speaker, but my second job is as a singer so I'm used to being in front of people and I'm confident I could do a pretty good job. If you choose me to speak, I'd welcome your feedback on my proposed structure.
Looking forward to the meetup!
