How do you filter content from steem blockchain to have only pics ?

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?

We're currently working on a website and hope to announce alpha version soon.

I don't understand how to register an account. What is a posting key?
ps ok. i have found it in steem settings
pps but still says - invalid posting key

Thanks for installing Steepshot!

We can see 3 possible reasons of your issue:

  1. The posting key has been incorrectly typed or copied
  2. Your username (korneta) has been incorrectly typed
  3. Public posting key was used instead of private

Please let us know if that was helpful.
