Late to the party...
Hello writers!
My name is Adrienne and my writing/publishing/marketing life has been kinda bonkers this year because I moved from FL to the Midwest, so "fish out of water" and all that.
As for the ebook situation, Evan makes a lot of great points and I don't know if my perspective will help much. I have an epub version of my novel out in the world, but I don't have a Kindle/ereader and I don't read ebooks myself. I just don't care for the format.
That said, if someone is curious about my book but might not want to pay to take a risk on me and my work (which I completely understand, especially in this economy), I send them to Hoopla, where they can download a digital copy of my book for free through their library. That way, I feel as though I am offering something for free and encouraging people to utilize their library resources at the same time. I know not everyone has access to Hoopla, but its better than nothing. And, if we're being honest, I'm cool sending people away from that rainforest company rather than to it.

Nice to meet you. I just realized how unfamiliar I am with Hoopla. I use Libby to rent audiobooks from my library.
