After Steemit.com, Busy.org, Steepshot and Others...
I just noticed them appearing on steemprojects.com this morning. I was curious so I looked deeper into it. It seems to be a new front-end developed by Nio Pomilia as the CEO. The only information I was able to find about him was that he is a
"Sicilian-American entrepreneur, forex trader, and innovator, with sufficient experience in the social media and blockchain space."
Encouragement
I love seeing new apps coming online on the steem blockchain and I think that we have a particularly bright future when we can see all those projects actually going live and doing real stuff...rather than pie in the sky ICOs on Ethereum.
@Blockchan - How are they different?
We have yet to see that. Their app or app preview is not ready yet and the description of the project is so generic that it's difficult to see how it is going to differentiate itself from the already existing steem front-ends. (See all steem front-end projects here) Even their logo seems to emulate steemit.com brand colors.
WHAT IS BLOCKCHAN?
Blockchan is a new, upcoming, revolutionary—and decentralized—social media platform innovation, built on blockchain technology. To be more specific, our platform is built on the Steem (STEEM) blockchain.
They may have done a better pre-launch by simply having a "Coming Soon" page with a newsletter sign-in form. Because all I see right now is a half-baked website with bad sales copy.
We shall see...
This project seems to be very new and we have to give everyone a chance to prove themselves. To give them credit, they haven't been making promises and hyping their project to get upvote ahead of product release. They plan, I think, to launch on April 1st of this year. From there we will be able to see what 
My opinion is that it is going to be difficult for them to attract a solid userbase if they don't completely differentiate themselves from the already established competition of steemit.com, busy.org or steepshot.io. They have to come up with a new way to interact with the steem blockchain that makes people excited and engaged. I hope to be happily surprised.
