I've also had to deal with loss of traffic to my blog. I don't know if it's my message on the loops, or the fact I've had authors I've never heard of requesting interviews and don't know if they're posting their own promos. I can only do so much.
With that said, I don't think I'll send out any more invitations, other than the authors I DO have relationships with. Cindy's already gotten more comments in the past two hours than some authors have had in two days.
And I just got an email from a promotional manager, wondering why her author wasn't featured today. I can't post something I never got! I told her I had another author on standby for next week if I didn't hear from her other author. Again, there's only so much I can do on my end.
