Absolutely. There are even tools for that like Share2Steem that allows one to autopost to Steem any content from Instagram, Twitter or YouTube. I once explained what Steem was to some people who were discussing monetizing their photography on the YouTube channel of Nigel Danson. Some complained they got almost nothing out of putting their photos for sale on stock photo sites. Nobody commented or liked. Morons. Thanks to posting my pictures to Steem almost on a daily basis for the last six months, I've made a few dollars worth of tokens per one set of 5-10 photos (organically + from @ocdb). That's actually more per day than one guy wrote he had made from stock photo sites ever. And he'd been at it for as long as such sites have existed. That guy was older than I am and he had had photography as a hobby for decades and most likely is a much better photographer than I currently am.

I've told several people I'm ready to hold their hand to get them started properly. I have a feeling that it's going to take some time before people are ready for this. At some point when the internet giants have had their reputations tarnished in enough scandals early adopters will begin to look for something else. Perhaps it takes more publicity in mainstream media. But when the early adopters come, we may be quickly drowned in people wanting in.
