yeah strongly recommended for algo ! he already build @share2steem a working product and consistently doing updates! though s2s haven't get a super mega huge youtube influencer like pewdiepie, it's slowly reaching out to influencers on youtube, instagram and twitter providing a ease of transition for users on these popular social media to easily share their content to blockchain platform steem.

what's the benefit for these content creators ?

1. expand content creator reach
2. another possible source of revenue
3. like dan mentioned, censorship resistance currently working for insta and twitter, for youtube s2s probably need more financial resource to have IPFS storing the videos

Here's 3 youtube influencers with 119k, 149k, 91k sub using s2s

like you have mentioned, there's only benefit for content creator to share their content to more than 1 platform maybe if followers of pewdiepie can share with him about s2s and how easy he can share his content to steem chain just by adding 1 single tag on his youtube video.
