What are your thoughts on platforms for fiction writers? I certainly get it for nonfiction writers (whose product isn't really a book but themselves and their ideas) but I'd rather spend my time writing.
Does a fun, amusing blog increase my presence when it comes time to query?
In answer to your questions:
(1) Fiction writers do not need platforms.
(2) No, not at all. I don't stop what I'm doing to look at author's websites because they're mentioned in the query. You can mention you have a blog, just like everyone else seems to, but don't direct me to it, or worse, require me to visit it to get an actual summary of your work. Then I will just be angry.
