So I really think this is a million dollar idea. And since this is a blockchain I am claiming it as mine in this post :p. If we make a profile page for steemit that comes with an avatar we can have blockchain clothing and accessories that you can dress your avatar with. You could also have a unique pet. It would be like crypto kitties but designed so users of steem can personalize their accounts.
We already have already seen how successful steem monsters was, people are ready to collect things on the steem blockchain. This will let them build an avatar and trade/sell the items they are wearing. And the money from the items that are sold by steemit can go into advertising or by burnt.
Plus we can have the option to design our own and add them to the store in set numbers. That way people can create pets and clothing and sell them in the store. This could be a job by itself for those who do not want to blog. And with pets we can make them as complicated as we want to really add depth to the collecting.
This would really make steemit stand out in the social space.
