I think if a project like ours ever did use blockchain, it would be behind the scenes as a part of the product; decentralization and transparency are key parts of our ethos! However, it's too unstable and as you can see by the comments, mentioning "web3" costs a lot of credibility in many, or maybe most, communities online.

https://knish.io/ is a good example of people using blockchain to make real products. I don't know that it's ready though.
