You guys should know what YouTube is already, but just in case you don't, YouTube is a website on which people can share videos. People from all over the world can post videos, and there are also videos from famous people, such as music videos. Anyone can join, and it's FREE. You can go and subscribe to people who post videos, and that way you know whenever they post a new video. You can comment, rate, favorite, add certain videos to a fully customizable playlist. Here is what I think about YouTube:
I have been a member of YouTube ever since the first day it came out. I still love seeing it be updated and move along with the world. There are updates to the website's layout and features very frequently, and every time it's changed, it's very convenient. Some of my favorite features at the moment are:
-the ability to choose the resolution of the video so that it runs smoothly with your type of computer. You can pick from 240p, 480p, 720p, and with videos that were shot with an HD camera, 1080p resolution.
-the ability to have a fully customizable playlist with your favorite videos.
-the ability to subscribe to your favorite uploaders (channels).
It all really adjusts to what you like, so I think that you should check it out if you don't know what YouTube is, or if you watch videos on Youtube, but haven't signed up.
