On: 3Doodler: The World's First 3D Printing Pen

[andrewfelix]

Awesome product, but ridiculous product description.

Also; "I'd like to see you try to make one..." is a silly counterpoint. If we applied that line of thought to everything we wouldn't be able to critically analyse anything. There would be very little discussion in HN comments.

I'm sure you've made criticism of products or services in the past that you personally would be unable to produce or deliver.

His point was more regarding those who have made silly criticisms for the sake of making criticisms rather than those who have found genuine faults with the product.

To use a practical example, in the New Scientist link for this product (which also made the front page), one commenter stated how the structures drooped a little and then commented that perhaps some kind of magnetic field could be used to hold the plastic in place while it cooled (he was more specific than that, but I can't recall the details).

That guy spotted a flaw and offered some of his own insights which subsequently sparked an interesting discussion based off that. Where as "this isn't 3D printing" and "this is just a glue gun" are unconstructive and, quite frankly, just nitpicking for the sake of nitpicking. The latter comments are as if people want to be seen as knowing better than the designers of the "3D pen" yet without risking their own reputation, money nor time.

And that's why some of us get annoyed when we see some pessimistic comments (not all pessimistic comments as you do also need constructive negative feedback to improve) and just wish those guys would focus their own frustrations into something constructive instead of knocking everyone else down.
