Hi Mr. Ploppy,
While we do have 2 ways authors can generate revenues (donations &
advertising revenue sharing), the vast majority of our submissions come from authors who's main goals are:
1. exposure
2. feedback
3. build a fanbase
Due to our popularity (3.4 million members, growing by 3,700 new members/day) we can facilitate the above.
We realize this model isn't for everyone, but those that decide to share their works through us are constantly pleased (in 7 years with the company I can hardly remember any complaints).
Hope this helps and have a great weekend!
