Yes - an on-platform store/hub or at least a link to one from your own blog/wallet should have been one of the first things incorporated into the site. Having a currency that you can't use is pointless. And the ways to "gamify" the platform with virtual trinket collections are numerous.
First, though - we need the development to happen. These features have to be created. Basic personalizing of your blog doesn't even exist yet. If that can be expedited, then the virtual store can be implemented. I think it would go a long way to attracting/retaining users and - more importantly - burning some of the huge amounts of the current Steem supply.
Just having places like Peerhub linked to the blog/wallet function would be a great improvement. I'm not sure why something that simple hasn't happened yet.
I was wondering if you'd seen this. It goes along nicely with your most recent blog about customizing features. I think you two should roll with this.....
