I like to suggest you to open up your questionnaires here itself, so that forum members will be easily check and answer them. For security purposes, people never prefer clicking links posted here.
Nah, some links are totally fine. For example links from a well known survey sites like SurveyMonkey or Survio, there is no risk in clicking that link.
Op, you failed to post the link. It is because you are a newbie and some links might be automatically be removed by forum anti spam script.
I suggest you post your link as plain text or with spaces.
Yes I do see some people are conducting using google spread sheet itself. I guess that would be more convenient way of collecting opinions. For polls, bitcointalk itself has facility and I am thinking to raise a request to Theymos for providing any possibilities for having survey kind of templates here in bitcointalk itself.
Because that will help people to study on bitcoin ecosystem which will be helping bitcoin to be promoted to new people effectively.
