But in case the author of the page is in here, please read the following:
Some years ago i had a similar idea, just instead of ruby-cons i went for defcon videos. I build a page that indexed all defcon talks and even tried to categorize them in terms of topics and difficulty. Added a nice search, and put it out as "defcon.video". It didn't take google long to message me and tell me i had to take it down because its actually forbidden to host an alternative search index if you are using the youtube API. You are not allowed to store the results of youtube API (longer than 24hours if i remember) and as stated before not allowed to offer an alternate search.
While you might argue: why didn't you just state that you don't use the api to grab the data and shutoff the token usage : well because google is not really known to be friendly and i expected them to just close down my whole developer account if i don't follow.
So - in case not all the videos are hand inserted (and even then they might come at you) google definatly will reach out to you and try to force you down. Back when it happend to me i didn't have the time and patience to fight them back so defcon.video was shutdown.
Best of luck tho
