Thank you for the link. It looks like an interesting series.

Now that I think about it, we don't need the Steemit to implement these features. Everybody can come up with their own website and/or app to access and use the Steemit data, which is on a public blockchain anyway.

Steemit.com is just one of the ways to access the underlying blockchain. If you think about it, it's just a proof of concept project.

I can easily think that another website/app combination coming up with a much better way of interfacing the Steemit blockchain and becoming the number one interface to it, taking over Steemit.com.
