This is extremely interesting. I actually kind of hate giveaways on blogs, especially when I go visit a new blog (based on the title or posts here on BF) and I'm all excited to see it. When I get there, the last five posts are all giveaways and "follow me" memes.
I never follow those blogs. Ever. I want to read something fun, uplifting, stimulating, whatever. Not stroke the ego of random strangers. I will be glad to see giveaways and contests parred down a bit.
