I'm curious as to how you decide what is mandatory for someone to enter your giveaway?
I've seen some bloggers who require folks to 'like' facebook pages, tweet, follow on GFC (google friend connect), AND leave a comment for a prize. Do you think that's fair? Just curious.
It's bad form, in my opinion. Having too many MANDATORY entries makes it all about you (the blogger) and not about the reader. Why should a reader have to do all of that? A better approach is to keep it simple. ONE mandatory way to enter and then whatever you'd like to do for the rest.
Sure a blogger should reap a benefit from a giveaway but that many requirements looks like it all about ME ME ME and not about their reader.
