Allow me first to clarify that the poll was created on request from another member whose name I just cannot recall at this moment. I think it may be one of a couple people, but I can't remember for sure, so I won't say. I would have to scour my chat logs to find out.
I do not believe that this poll is too far off topic, because someone posted a short while ago the PayPal coupons to which the poll refers, and they were believed to be useful to our members. The poll's presumed purpose is for the original author to guage whether or not it might be worth his or her time to seek out future PayPal coupons and post them here for the benefit of our members. I'm not sure where your point about polls being limited to only a few people comes in.
With regards to whether or not people use a Visa card, I think you may be creating a somewhat unrelated example.
I hope that this serves to answer your questions, and I would welcome any further discussion you may have on the subject.
Edit:
After I wrote the above, I noticed a PM from Martin reminding me that he was the one who asked for this poll to be created. He says that you can contact him by PM if you would like to discuss it.
Thank you, Martin, for your message.
