Why would people have any reason to use Facebook, Instagram, Snapchat, Twitter or anything else if Steemit just made "Steemier" versions of the main selling points of each website, into a feature of Steemit.com? There is room for more than just upvoting articles around here! Status updates, Photos, Videos, Custom Profiles & so on!
A Steem Profile of your very own. Full of editable fields, areas for pictures to be posted, etc.
I can see it now, my very own Steemit.com profile with loads of information about me, a few featured posts that I chose to add, perhaps a custom theme or something along those lines for the header area, and best of all, my very own Avatar/profile picture! That sounds like a platform I once used in the past cough Myspace cough but it sounds like the best platform to build on top of a wonderful Blockchain such as this.
A Historical Steem "Facebook Wall" (after followers get implemented obviously).
Everyone has the countless family members who "don't use social media" but still have a Facebook account where they occasionally login and post an update about themselves or whatever else and they might scroll through the news feed for a moment but thats about it. If we want these folks to be included in the Steemit future, we should consider this now and just add a personalized feed for them and as a way to compliment having a "news feed" of sorts in the form of a blog for them already.
A Steem "short-feed" where people can post 300 or so character posts as mini status updates as opposed to articles.
We could take a shot at Twitter and get people paid for their short newsworthy content, thus creating the de-facto place to share news as it's happening, and get paid at the same time! Imagine how many reporters would come here first with their breaking news instead of go to local news stations if we had this system...
Your Very own Steem Photo Gallery!
A basic addition to the "custom profile" thing, basically just store some settings and/html in the Blockchain just as you would for a post, but pull from that specific post for profile settings and such, using this you could literally host full image libraries and create a Steemit Photo Gallery! The Blockchain might bulk with this feature a bit, but its just more text at the end of the day.. still no photos hosted on Steemit or the chain..
And last but not least, a Steemit version of a sort of p-2-p photo messaging platform, most likely a 3rd party thing though.. images and all.
