YouTube is one of the largest and most influential tech companies in the world, and wields huge social power. Some of the greatest content on the internet is hosted there, so it makes sense to me that HN readers would find a major change like this of interest. Wojcicki has been in charge of YouTube for a long time now, so hearing that she is stepping down and will be replaced opens up tons of space for speculation about where YouTube could be heading in the near future. Personally, as someone who spends many hours a week using YouTube, I find this article to be absolutely HN-front-page-worthy!
If it's in the company of curious, smart people like the kind I routinely encounter here on HN, then yes! Absolutely! I greatly enjoy a good round of civil speculation and discussion with my fellow hackers :P
* There's absolutely nothing we could do to influence YouTube's leadership changes.
* There's very little you can do to influence changes in the product YouTube as well.
* There's very little we know about the internals of upper C-level leadership changes.
Speculating is an utter waste of time. I don't see a point. For me this news was just another passable piece of information. Meh! Definitely not HN front-page worthy.
