Are there many talks about a single person's vim config? That seems like a poor topic to me, and I'm not sure how many people would consider it a good idea.
It just a lazy analogy for many useless talks. Btw, I LOVE talking about my vim config in a small setting like a 10 person meetup just because I LOVE vim and like to be with like-minded people. But I'd never do a public speech on it because it's no achievement and more important: my vim config is not my identity (maybe a bit ;)
