There are also sister “apps” to Steemit that work within the Steem blockchain. These include DTube (a YouTube alternative), DMania (getting paid for memes), DLive (for live streaming) and Zappl (a Twitter alternative.) My very first Zap just read: “This is my very first Zappl and I have absolutely no idea what I’m doing,” and it earned me six cents. You can learn more about these apps by reading the Steemit story here. Steemit also has an active “in person” community, including a Steem Creators Conference that’s coming to Las Vegas in mid-April.
Secondly, there are regular competitions or "Missions" with specific briefs. Prizes come in various forms such as being published in an exhibition, having your work used in commercial campaigns, or cold hard cash. This is a great way for marketing teams of commercial brands or exhibition curators to hunt for new, enthusiastic talent. This gives any aspiring photographer the feeling that the playing field has been leveled, and if the quality is there, then you wont be ignored.
Flickr has strong organization tools for your images, being able to bring together collections into "Albums" rather than having just one feed. Flickr also has a "Groups" section that are open-sourced public albums. This is a nice way to find collections of images of similar topics, themes, gear, or geography, but these "Groups" are too often messy, unfiltered, and unorganized.
A simple chat (slack style) it's enough. Just having the possibility to send messages either single user or team (#channel). But please don't forgive to give an useful appeal to mobile app (worst error of competitors is, have a good app but totally no mobile friendly!) i would expect to have a similar whatsapp or slack app for messaging within the slack mobile app!
