yeah anything posted to dtube automatically is posted to steem blockchain as well, which you probably didn't realize but just figured out! It is nice they have the youtube upload method in dtube now, it makes it easy to do one post on dtube and still have the youtube video available to watch on the related steem post as well. one thing to point out, dtube does often mess up the tags you use in the post it seems, so you might want to take a look at the post on steem after you post on dtube to make sure all the tags you wanted to use appeared.

One other tip, if you use steempeak.com as your steem front end it allows you to use up to 10 tags (instead of the limit of 5 tags that steemit.com has). This is true even if you just edit a post using steempeak.com, so you could open up the post created when you upload to dtube, edit it in steempeak.com and add more tags.

Since you were last posting here there have been a lot of developments, including a bunch of "sidechain" tokens launched that allow posts to earn more than one kind of crypto - for your own posting I would recommend using the #creativecoin tag which would make your posts eligible to earn CCC (Creative Coin Crypto) - your posting will go over very well with the creative community! You can learn more about the sidechain tokens at steem-engine.com, and check out creativecoin.xyz website which is a dedicated website displaying only posting with the #creativecoin tag. I am a creative coin "whale" (large stakeholder) so my own upvote is actually worth a lot more $ in Creative Coin than in Steem (you can trade creative coin and the other sidechain tokens against Steem on the internal exchange at steem-engine.com). Let me know if you have any questions. Cheers
