I have also posted my novel on RoyalRoad, and honestly, I'd suggest it to anyone on this site! The only real flaw of RoyalRoad is that it has a rating system which I hate, but otherwise, I almost got as many subscribers on my story, Inheritance, in one month on RoyalRoad which took me like, four months to accumulate on Tapas. I find that reader interaction is much better on that site, too, and blessedly, the site lets you keep your italics when you copy and paste your document! The format is prettier, too. XD
I haven't gotten into the community so much at RoyalRoad, but I have to say it's a much more writer-centric than Tapas in the way that writers get a lot more love and that there's a lot more variation in what's popular there.
But, I still really love the community on Tapas <3
My novel is Inheritance! And my favorite chapter... Hmmm that's difficult. It may not be my favorite, but Docile comes to mind. I don't normally like to give myself compliments, but I think it's a really sweet and romantic chapter without being too unrealistic or corny. I also think it establishes Eory's and Pollyanna's relationship very well--so I will give myself a pat on the back. ^u^
