I enter quit a few of the giveaways if they dont reguire a lot of time, I am totally with boho hippie mom, I will pass up those giveaways that have a page of twitter ids, FB, G+ to follow. I know we charge for and create large giveaways by charging for those wanting to participate in these giveaways, but gees who has time to spend at each giveaway filling out all these things and then as part of that giveaway make you enter another giveaway to be eligible to win the first one.
I am about ready to go back to just sponsoring my own giveaway with a plain linky, with a drawing by using random.org and asking the visitor to follow, tweet, and share. The whole reason we have these giveaways is to build our followers, gain Alexa stats because of visits and page ranks. I love your post and it got me on a soap box, sorry but thats my opinion.
