In my opinion, which is only worth so much, no, you shouldn't have copied the text from YouTube.

Steemit is different from all 10,000 of the sites you mention. Steemit gives people a place to earn money for posting "valuable content" (which is a relative term), but it's a lot more than that.

If people just copy and paste the same content from other social media, we're just gonna look like other social media. Steemit is supposed to be different.

I have no problem with people sharing a link to a YouTube video as part of their content, but explain it in your own words. Talk about why you're interested in the video in the first place. Talk about the subject of the video. Talk about the people in it. Steemit is about being rewarded for original content and ideas.

The same ol' same will be the downfall of this wonderful community.
