Wattpad is for anyone with an interest in books. It is reader/writer social media and it is free to join! It is an excellent way to reach your readers and get feedback and comments on your work. wattpad is mainly a YA scene so if your interests or writing genre is outside of that realm it might not be for you. If you publish your work there, you are essentially giving it away for free too. I wouldn’t recommend just publishing a taster either- users on wattpad want the full version and if they only get half of the story, they probably won’t be interested in following you.
I have published a few chapters of Ruthless there and I will be slowly adding more each week: http://www.wattpad.com/47288277-ruthless-chapter-1. Posting on weekends is a good way to pop up on current content searches. I haven’t really had much success with comments and feedback yet but the most valuable feature for me has been being able to track the number of reads on each chapter and my synopsis. You can actually see how many people ‘read on’ which gives you an indication of the strength of your writing.
If you would like to connect with me and give some feedback on wattpad I would LOVE to hear it.
