No, it's not set as my home page, but here's why not. If I opened YT first, I might as well not have the rest of the internet.
I would get sucked in right away and never leave. So I do get a bit of news and/or do whatever I set out to do and then am rewarded with YT. THEN, I'm a master at multi-tasking, so I can then do several things at once with YT being one of them.
