Yeah, it just depends for me. I'm not a big fan of spoilers, but a lot of times I really do need more than just a short blurb to convince me to read something.

I really wish more people on the SGA Big Bang comm would use a rec for their preview. I'm finding the authors have no idea how to promote their own work (at least the ones who have posted so far). (Tip #1: If your story is novel-length, you need to write more than one vague line for your summary.) A long rec that really went into what makes the story interesting and different would be immensely helpful.
