For alpha test version, we're using regular expressions to parse picture URLs out of the content of existing Steem posts and showing the first picture from each post.

In future, we'll only show the content created by our application, filtering out the content made by other clients.

That will be cool - I think having apps that create their own posts will actually be better in the long run - it will allow each app to create it's niche and reduce content confusion.

Probably by allowing only four tags, with "steepshot" being an automatically added tag, which is checked for before loading it into the application on the user's phone.

But I dunno, I'm not associated with them.

Yes, as you've mentioned, we'll use filtering by "steepshot" 5th tag or json_metadata steepshot "app" label (or both).

Oh, I'm happy I was right then.

But must this use the existing Steem blockchain?

It might be more reasonable to start completely from scratch, and create your own currency, even if it's just ported from Steem's code.

Building lots of apps on the same blockchain is a good thing, not a bad thing. Metcalfe's Law means that the networks will benefit in terms of value far more if they're part of the same one rather than fractured apart.

We're moving forward step by step with current focus on mobile and web clients for Steem blockchain.

Although we love Steem, we don't exclude the possibility of moving to a separate Graphene-based blockchain in future.

What would be the benefit of creating another blockchain?
