### Is Quirky a scam?November 18, 2010

I paid my \$10.

I wrote all about the ZeroSum Ruler.

I submitted a picture, wrote my bio, wrote all about the ruler, and…..

Nothing.

No really, what is “Quirky”??

Still, I did manage to see that five people, probably unemployed and bored, decided to click on my product number to see what it was.  Here are their comments and my replies:

Becky Blatchford:

“I like this. If it is inexpensive enough say under \$10 I’d bet moms would buy this up!”

Me:

“Thanks Becky.  Hopefully they will when more people find out about it.”

socrtwo:

“Interesting and simple.”

Me:

“Thanks scortwo”

Michael Kloeckner:

“I love it, I cannot believe this is not out there somewhere”

Me:

“Thank you Michael. Now only to find a venture capitalist to back production and marketing!”

Dave McKey:

“I agree with Aaron. no need to fold the ruler.  good luck!”

Me:

“Thanks Dave.  I’ll think about the fold.”

Aaron Dale:

“I watched the video on your website and the only question I have is, why fold the ruler? Just make the ruler so it has negative numbers along one edge and positive along the other edge. But if a kid can use a tool to combine negative and positive numbers, they should use a calculator. It would be best for the kid to understand why they get the answer they get instead of counting the difference on the ruler. It seems like cheating.”

Me:

“I see what you’re saying about the folding.  it would be a lot easier to make without the fold.  The reason I made it fold was so that it starts out looking like the normal numberline the kids use in school.  The folding then shows the relationship between negatives and positives.  When a kid tells me -22 + 5 = -27, there’s a problem.  When this kid is in 11th grade, there’s a bigger problem.  When this kid is not just one kid but many, we’ve got a huge problem.  My thesis results are in and the ruler caused students to make 1/2 the mistakes as before the ruler.  True, data isnt’ everything, but I never thought it woule make such a difference. ”

So what is Quirky?  Can I build a website, undercut Quirky by charging anyone with an idea \$8 to write all about it only to have it disappear into a “relist” button one week later?  I mean, everyone has an idea, most everyone has \$8, this is the best scam going, right?

Am I missing something?
