Crossposting from Tumblr, is it worth it?

Question

Social media

Friends, welcome.
I re-read everything under the "crossposting" tag, found several convenient services, but I have a task that gave rise to an idea.
There is a person - he places everything on Tumblr, it's convenient and that's it. The opportunities there are excellent, but it took me to come up with something to make posts from Tumblr go to all social networks and not just leave, but also be formatted correctly.
In facebook and twitter, crossposting is great, because. This feature is built into tumblr.
So we came up with an idea, what if we write such a service that will publish and correctly format posts to all other social networks. I want to ask you - do you think such a service would be useful and in demand? It is the transfer of posts from tumblr.
Thank you.

Answer 1

It’s worth it, Yandex and Google see links from there, and this is already good. It is difficult to get traffic, there are few Russians there.
