Thanks for your entry. Both bloggers have been upvoted...well the first one had already been.
What I might suggest if you notice this again is either pick a different post if they have another good one or use that person the following week and find someone else. This will increase that bloggers exposure vs people coming to the same post twice and exposure is what we are trying to help the bloggers gain.
Thanks for the feedback, those are good tips which I'll keep in mind for the next time!
