Hi, thanks a lot for promoting our application (me and @sebbbl are behind the project). The website is https://www.share2steem.com
For complete informations about Share2Steem, please refer to the presentation post or the how-to guide.

Actually, YouTube is soon to be available for cross-posting to Steem but not yet (just a matter of a few days tops). But Instagram is fully operational and Twitter too (even if there are still some post-formatting problems concerning Twitter).

We also think that Steem is destined to be the all-mighty social network and shouldn't just be an obscure media for blockchain-based (or Steem-based to be precise) lengthy-or-not (I won't dare say quality here) posts. Of course there's a lot of great content here, and initiatives going in this direction are so numerous I won't cite them. But it's everywhere the same, a small percentage of exceptional posts and a vast majority of ordinary publications.

I totally agree with you. Why continue to think Steem is different than other social network and should only be reserved to "bloggers" ? When everybody is complaining about low-quality posts, bid-bots abuse and the absurb trending page ? Let's embrace our destiny alltogether ! We're meant to be the #1 social network and that means welcoming everybody, clever or stupid, beautiful or ugly, writer or illiterate !

First they will use our app to cross-post, then they'll only be on Steem and will leave their traditionnal medias. We all know here the addictive power of the Steem blockchain. We just have to push them a little bit for their first steps.

To finish this, I will just cite thou :

It is a great time to be involved in STEEM. We are going to see so much growth over the next couple of years. The tentacles of this blockchain are reaching into different parts of the internet. To be frank, it is amazing where some of the development is leading. Truly mind-boggling.
