Yeah it's pretty much a put-off 'cause you're being rather unfair to those who DID subscribe to your blog. Maybe you should take out that part of your contest, eh?

It's like saying "I have 6 pieces of meat to give to 100 of you, but if all of you don't agree with what I say, I will eat all 6 pieces for myself."

Rather selfish, don't you think so?

Don't say it as if you're desperate for readers. The more desperate you sound, the lesser people would be interested in your blog.

Sure, a couple of them would sign up, but I wonder if they follow your RSS feed because they're really interested in the offer, or whether they do it out of pity.

Don't. Sound. So. Desperate.

Cheers,
