YouTube is my number one streaming service as you always find something to watch whether it is gaming, music, art or whatever. I myself are a YouTuber and find it hard to get views and subcribers but my passion is making videos for others to enjoy. So it is a big thumbs up for me even though YouTube have strict rules.
The only good things about this site contrast all the "alternatives" is there's an audience there, uploads are fully unlimited for free (hey Nicovideo, who the heck limits bitrate?), hate speech is rightfully suppressed and it won't die in two to five years.
