You're right. The companies I was referring to were all blockchain-based. I cannot give you the best example, as I don't spend enough time on Steemit to be able to compare, but one that comes to mind (because I participated in their challenge) is Streamity. I noticed maybe one or two others recently, but can't remember their names. It looks like they all apply the same recipe via @originalworks. I haven't thought in too much detail about it yet, but I believe more specific tasks could produce more value for the challenger.

I think Steemit can be useful for a wide spectrum of companies. Just look at the breadth of topics covered by enterprising solopreneurs on here. Blogging won't go away. I just think that many companies leaped on it in the last few years as a tool for quick attention by providing pseudo-value. Now, there's so much mediocre content out there that people get bored of reading. Hence, video kicks in to entertain the general public and extract some sales.

To get buy-in from bigger companies, it'll require people (like you) who understand regular business requirements as well as blockchain/tokenization to make the transition easy and develop creative strategies. The complexity of Steemit is a tad off-putting for a DIYer, especially for newcomers - all those bots and vote-buying, Steem vs SP vs SBD... In contrast, companies already understand video. Once that's oversaturated, they may be ready to buy into a reward-sharing platforms like this.
