Lets see how Dave's work
The main thing is he made a set of contestants before it started (min 10 posts). In other words they were qualified before entering.
I would like to see non-profits be the only ones qualified to enter. Like schools. My idea is for a trade school like ITT enter because they may be able to use a high cost scope and in turn they would put something together (like electronic labs) for poor schools. They could use students to assemble kits and write materials.
Seems there would be a lot of good will to encourage a lot of publicity for KS and the trade school.
In other words it would be nice if a high value item could benefit more people. I also would like to see the benefit go to school labs in third world countries.
The trade school that could put the best third world lab together would be the winner. Blog members could help. I guess it does not have to be a school. A person (unlikely) or a company could do this.
I do not like FB contests. This one turned out to be kinda sad 
I hope this topic will encourage some good ideas.
Even though I am a big fan of Dave and what he is doing on EEVBlog, I don't thing he ran the contest perfectly. For one, even though I added my name on the forum, and qualified, my name was NOT on the excel list as he scrolled through the (presumably sorted by name) list. So I think there were a few who fell through the cracks somehow (bad SQL Query?). Also, I did not agree with the hasty way it was done - e.g. none of the two winners were online. I would have loved to see their reactions when they win the prize

@Daniel:
1. There was a bit of confusion about the smallprint in the beginning (aka. All your life belong to us!!!

Many engineers are very precise when it comes to lawyerspeak (it scares us!) That was bad.
2. The videos were fun, taught me something, and put a few faces to your company. That was great.
3. There was confusion in the beginning about entering every day, entering with multiple emails? etc. etc. A clearly written bullet list of what can and cannot be done (in engineer-speak, rather than lawyerspeak) would have been great.
4. I think the campaign worked on me - I was on the fence about buying a new scope, and now I think I will seriously consider Keysight scopes (though they always seem slightly above my budget).
5. Scope-month was great, but maybe having contests more often, even for much cheaper scopes, and on different occasions, is probably the way to go. there were plenty of my engineer friends who did not know about scope-month.
6. The scope barbecue was cringeworthy. You need to understand, for many people who have never owned an expensive scope, a Keysight scope is something to be enjoyed and worshipped (ok, maybe not "worshipped"). A lot of people saw that as sacrilege. There are ofcourse many here, and probably more at Keysight, who see and work with these scopes every day, and to them it was not a big issue. I think the lesson to learn is, to bring in a couple of people from your audience, from outside the company, and get their opinion if you ever want to do more "barbecuing"
