Reader Susan Kirkland chimed in with her thoughts on writing on spec based on this previous post:

Whether it's writing or designing, creative product on spec is always a losing proposition because the process exposes ideas, unprotected ideas, to unethical eyes that may be watching during the process. It's just a refined version of dangling a carrot in front of a horse. Though my interest is design, every aspect of the No-Spec movement is applicable to writers as well.

And there's a huge no-spec website.

I'd never heard of a no-spec movement! I hope those working on the website are getting paid.*

*This was a joke that needed to be made, not a reflection of any thoughts against the no-spec movement.
