I agree they could have a motive, being in a position to benefit
financially, but I don't know about the like mindedness of their
visitors... I'd guess you've got mostly buyers and design engineers
visiting an electronics distributor's website. Most of the buyers and
engineers I know think RoHS has been a royal pain in the neck for them.
Once again, I'm not defending the poll, just pointing out one minor
issue I don't agree with, mostly because things are slow today and I
like playing devil's advocate. Have a Merry Christmas!

I totally agree Mike,
Newark (I still call them JUST Newark), is one of my favorite
distributors, but they are in "the business", and therefore are very
enthusiastic about the RoHS initiative as a money making opportunity. I
can't hold that against them, but would imagine that the clients/people
surveyed would be of like mind. Just my 2 cents, as well as an excuse
to add the Off Topic.....
MERRY CHRISTMAS to all you Technetters!!!
Regards,
Dave

Jon,
I appreciate the thoughts, but you're forgetting two important things.
1. If the methodology is invalid, the results are invalid. That's a
simple truism.
2. Even if the polling was secure (i.e., 1 vote per person * which is
impossible to prove, btw, because someone like me who uses several PCs
could vote multiple times), Newark InOne is not such a broad-based site
that there would be reason to believe that a representative and random
cross-section of American electronics engineers saw the poll and voted.
Therefore, the results would be invalid due to what's known as a
sampling bias.
Sorry to get technical here, but we're dealing with a highly senstive
topic and the methodology flaws are too big to ignore.
Please note that none of my comments should be taken as criticism of
Newark InOne.

Mike,
I have to disagree with some of your comments. I don't think you can
say the poll is "completely invalid" just because of the way it was
conducted. It definitely wasn't scientific, but that doesn't mean it
was completely invalid.
Most polling software prevents duplicate votes from the same computer.
Although this isn't perfect since it uses browser cookies to identify if
you've already voted; which we all know can be deleted. Most polling
software also records the IP address of the person who placed each vote,
along with time and date. Most of these IP addresses can be traced back
to either a network provider (for small companies), or in the case of
most larger companies, it can identify the company by name. The
software I've used in the past does the track-back automatically and
lets you know the name of the company right in the polling results (not
seen by the general public, only by the system admin).
If they did their homework and reviewed the voting records logs in
detail, they could easily identify if someone was 'stuffing the ballot
box' - so to speak.

Oh come on, let's not even debate this "poll." It was conducted on their
website using the "methodology" of persons clicking on a choice of
responses. There were no controls over who voted, or how many times they
voted, or, well, anything.
The "results" are therefore completely invalid, and we chose not to
publish them precisely out of concern that readers might overlook the
data collection flaws and assume the "findings" correct.
The other problem is that few of my media colleagues understand stats,
let alone care. Bah humbug to them.

If RoHS-like legislation in the US States is inevitable, then it would
help to have national legislation rather than 50 different sets of laws.
However, if there is to be national legislation, can it ensure that the
States will not still inact their own, more stringent laws? For
example, if the US sets EU-like limits, what is to prevent California
from setting lower limits for substances in materials (as is their
propensity in such cases)?
Also, will the US propagate the same onerous process as the EU and
duplicate the many mistakes made by the EU? Will the US require that
standards be in place BEFORE the law goes into effect? Will the US
require sound cost-benefit research BEFORE a substance is restricted?
These and many more questions need to be considered if and when such
legislation is proposed.
