Navigating Indieworld Discussing All Things Indie discussion

I have it in my diary to investigate Wattpad today... Ahem. I know everyone else did this some years ago, but I'm still paddling in the shallows.

I've read a few pages on their site and I'm left wondering if it's not possible to upload a book to them and also be in Amazon's KDP.

People have spoken highly of it before but would you say it is a worthwhile thing to do?

Many thanks.
