Steemit is still a work in progress, and new features are being added constantly. For example, Steemit recently changed many underpinnings of how the network operates in order to help onboard new users faster. (Sometimes there is a waiting period before a new account is approved.) Stone told Heavy: “Hardfork 20 is going to improve the account creation process and user experience (post editing and voting, specifically) on Steemit and other decentralized apps on the Steem blockchain.”
App.Net was, I think, the closest we’ve come to a good Twitter alternative, and it came out back in 2012. It did basically everything Twitter did, but nicer. It had a decent web experience and a great selection of third party apps up and running within weeks of launch. And while it was a paid service (and maybe therefore doomed from the start), tons of people in the tech community went there and were having lively discussions. My App.Net feed was a joy to browse, and most of my Twitter friends were there. Oh yeah, and it was an app platform that let some devs build off their back end in interesting ways.
Imgur is one of the best alternatives to Instagram to share your images over the internet by just after a simple sign up. According to the stats, everyday Imgur is used by the millions of peoples with different Goals, some came to be entertained, some came here to share their masterpiece &  build connection and other came with other motives to this one of the best photo sharing site “Imgur”.
Polaroid's resurrection continued in 2016 with the release of their social multimedia platform SW/NG, and I'd put it down as one of the most under-rated social mobile platforms around. Forget Instagram Boomerangs, SW/NG brings pictures to life much in the same way Live Photos does on iPhone. Using the app feels similar to Instagram with the continued scroll of your feed, but pictures move as you scroll. The app feels cleaner than Instagram, and encourages users to think differently when composing an image given that a moving subject or background is more compelling.
Plurk utilizes a horizontal timeline, with messages summarized by single verbs (“feels”, “loves”, etc.). As you would expect, media files can be shared, and Plurks can be liked. Emoticons are an important element of the Plurk user experience, and your selection increases as your karma grows. Karma is based on your activity on the social networking site. Group chat and direct messaging are also featured on Plurk.
We would much rather prefer to use specialized tools (Google Hangouts Chat, Microsoft Teams, Slack, Atlassian Stride) that focus on being a communication hub and integrate with all the other software we use like erp, crm etc. So a focus on integrating existing tools would be very much preferred. And if you really would like to built a chat platform like e.g. Asana with the chance of being subpar, then please make it optional with the possibility to toggle it off.
