I would give you 1,000 upvotes for this post @roxane.
I am new to Steemit and I see the value of it. Personally I think it can become the new Facebook or Reddit, but it will take a lot of time and it all depends on us as a community.
It saddens me to see people posting about everything from personal development, to blockchain, to celebrity gossip to sports, and so on just for the sake of money.
In my newbie opinion, a valuable Steem user, is the kind of user that writes only about the things he has a real knowledge about, supports the projects that help the community (e.g. @curie @sndbox), and helps the platform gain exposure through their personal network in other distribution channels.
I hope to see more posts like this from you! Even if it might feel that your efforts doesn't matter, they do! Thank you!
