It has been relaunched, and I did join up, but haven't been back. Steemit and all the tribes and servers and tags and blah blah blah have me spending far too much time and mental energy trying to understand and keep up (not to mention the HF's)
But you can check out the link
Tsu was originally launched on October 21, 2014. The first version closed down in August 2016. In 2019 the relaunch of the platform was announced with a more sustainable version (the original concept was to share 90% of the gains of the platform with users. However, this model failed because it couldn’t afford the project’s costs).
The main change in the business plan of the new Tsu was the percentage of revenue distribution (from 90% to 50%). In addition, the project also promised to be more aggressive in marketing and partnerships with major influencers.
