Serializing/Posting Excerpts?

[Sally]

Do any of you visit, belong to, or post your books on Authonomy or Wattpad as excerpts and for getting/giving pre-pub comments/support/reviews? Experiences? What are the best sites (besides my own blog) to serialize my next Volume (sci-fi/romance/paranormal/multiverse/utopian for adults/new and young adults) starting in mid-March through early June? Thanks.

I asked this on several group pages about 30 minutes ago.
So far, more votes for Wattpad than Authonomy, which is the opposite of my experience last summer/early fall, but that was for my first book, This Changes Everything. For Vol II, I have more contacts, readers, maybe even a fan or two, so things may be different.

I plan to excerpt/serialize on my Series pages via my own blog on Wordpress and Tumblr which goes on both FB and Google + (I only had FB series page for Volume I) as well as my personal pages on LinkedIn and FB, and on both Authonomy and Wattpad, but I wondered if there were other options, out of my own network, so to speak? Ideas welcomed! Sally Ember
