My LibraryThing authors are:
Sandra Gulland (Josephine Bonaparte series, of which I've only read one)
Maggie Marr (The Hollywood Girls Club)
Marisa de los Santos (Love Walked In and Belong to Me)
Lori Smith (A Walk with Jane Austen)
Sarah Smith (Chasing Shakespeares)
Lisa Unger (Beautiful Lies and Black Out)
Melissa Walker (The Violet Series)
Laura Parker Castoro (ok, I'm not sure how she got on there - I've never read any books by her!)
I have talked to an author once, LT was doing an author chat with Marisa de los Santos for about two weeks. I asked her about her beautiful writing style and where it came from.
I've never received any comments from any authors on my LT account, but I've received a few on my blog!
