Sorry, I should have made that more clear! Nothing on the block chain, I meant platforms such as YouTube and Vimeo. But when you say it like that I realise that they aren't really alternatives as they are completely different platforms.
I guess what I meant is alternatives for viewing, as for the viewer it doesn't matter if it's on a block chain or not, as long as it works and is pleasant to use.
I tried to watch some videos yesterday and they stopped in the middle to buffer :/ When they can fix the speeds I will love DTube though!
