Not the person you asked, but I am always consistently surprised at the success of survey monkey. I was a paying customer for two years though, mostly for reasons of replicibility. Many, many, social scientists use it, even though it doesn't really support useful things like randomisation to entirely different surveys.
The interface is nice, and they appear to have sewn up the marketing world, so well done to them. I still want to build a much better version, but I'm not sure if there's a market for it.
I know this might seem kind of silly but isn't the success of survey monkey a sign that there is a market for what they offer?
Unless there is something I'm missing, kind of like there are markets for medicine and the system could use improvement but there are major roadblocks to overcome (in this case I don't know what it is which is why I ask).
Well yes and no. My idea is a little different, but I'd need the SM crowd to be able to have enough revenue to build it, so my worry would be that I wouldn't be able to get enough people to allow me to work more on developing the part that I'm sure there's a market for.
