Well Hive account@silky-unicorn597 you should not do that as you will be annoying your genuine followers with the same content. Try and change it up and also add something more to it for each platform.

Think of it like this...

1. Steemit.com - Write a blog here add pictures and as much information as possible to make sure your message gets across clearly to anyone reading it. This could be a tutorial or a story to share or anything random. Just write and add pictures to express your message as clearly as possible.

2. Dlive.io - Film a live candid video of you talking about the object. This your opportunity to be one on one with your followers, the time to make a connection with them. The reason people subscribe and come back is "YOU"!

3. D.Tube - Now here this platform I would suggest using it to upload videos you have put a lot of work into and want to take it to the next level of expressing your message through video form. Because this is not live, this gives you the opportunity to put more flare to your video, through post production editing. Once again another opportunity to showcase your artistic talent and also have a better connection to your followers.

You can even go a few more steps further and add photos from that post to SteepShot application another Steemit application but only for photos. Also if their is audio say from an interview you did you could take the audio and start posting that on Dsound.audio another application on Steemit but for audio only.

Hope that helps!
