John Chow is giving away a dual-monitor video card to a lucky reader - all you have to do is leave a comment by the end of today.
I’m not sure that it is the first time it has been done, but it is the first time I’ve seen it work so successfully. My comment was number 418 (I think) - the reason I cannot tell is that the number of comments gets in the way of viewing the whole comment set 
People love free stuff, and it is something that Seth Godin wrote about in Free Prize Inside. In consulting, we call it overdelivery - give the client more than they expect, and they’ll be impressed enough to ask for you next time.
I have been entering John’s comps too, but i can’t keep up with them - it seems to be like one a minute.
Personally I think he is a bit bonkers but I love his blog - especially the eight things you didn’t know about me and his serial killer schoolfriend.
I have put a comp on my site, but it doesn’t require any free links or comments. Just thought it might generate a bit of interest and also give a bit of a plug to my friend who is a new designer.
Hi Catherine,
thank you for your comment. I’m running a contest myself about a niche for BlogFuze.
I’ve entered your free header design competition and look forward to hearing more about your blog as it grows.
Best regards, Andrew
