dtube is still very much in development, and when I tried a few times nothing I tried to upload would play for some reason. I think for now it's something you have to keep trying and if it works great - if it doesn't go back to YouTube - you can easily embed YouTube videos in here by dropping the share link in your post - what I tend to do is screen grab a few stills from a YouTube video and add some text to create a post (see my blog for my weekly vlog posts) and then end it with the actual video link which can be viewed straight in the post. Not sure anyone watches the video but at least it creates a meaty post!
Yeah I've seen a bunch of changelogs for dtube already -- definitely in flux still. I would imagine with the hype around VR in general, 360 should be supported eventually. Thanks for the tips on the youtube stuff, as well as making more substantial posts. I'm trying to steer clear (when I can) from just posting a single picture or video link, and two sentences.
