I use YouTube because you can find a lot of interesting and informative videos out there.

YouTube exists since February 14, 2005, and peple post around 3 million videos every day. Now imagine how much content you can find there.

Also, recently, a new thing appeared there, «YouTube Shorts». You can watch short, but still exiting videos there, just like on TikTok.

That is why I use YouTube.
