Tapas is friendly, yep. People are fun to discuss with and they support your work. I made friends already and it's just been 2 weeks.
But you will not get the readership people in Wattpad used to get 2-3 years ago. As long as the story was updating regularly, they saw a steady rise in readership even reaching to a million (I personally saw one story get there). Since this site is new and Wattpad is crashing down like crazy, you'll find yourself in a restless middle place where readers are comparatively scarce on both sites.
BUT. I see potential in this site. Like @mcarrowolga mentioned, the community is interactive and pays attention. Over time, I'm hoping Tapas to flourish.
