I pinned a post showing my novels’ quotes and links to my Wattpad and Tapas on Twitter, and I talk about other things. If people want to, they will check it out by visiting my profile.
The same with forums—I talk about what interests me, post quotes of what I am working on, and if anyone gets intrigued, they can click on my profile and see my story or stories. No obligations, no asking, because, well, why force it?
I tried to do more in the past, posting pretty quotes on twitter and Instagram with clever invitations to check out the chapters, but it doesn’t really yield results, except, possibly, that I now despise Instagram, while before I found it mildly bewildering. My accounts are small, and frankly, I don’t think people who don’t know me, see it.
I also doubt the world has that many people left who are not already here and who desperately want to read free web books.
Tapas already shows me in fresh when I update. From there, it’s up to people to check it out.
