First off, thanks for taking the time to contribute!
Create a PR and follow the same markdown format as used in the list. If the talk is deemed interesting enough we will add them to the list.
There are no true guidelines. The talk mostly has to impress me on some level and is preferably about technology I find interesting.
This is just an easy reference list for me to link to people I meet who are interested in a certain (tech) topic.
When visiting several conferences and meetups, I kept referring people to video's I've seen about certain topics. As it became quite tedious to keep a log of them all, I just started a list.
