Then the Wufoo example is mistated in the blog. The feedback was useful for deciding on interface changes but not useful for deciding on platform/technology changes which is what it seems to imply.

So I'll change what I said...It shouldn't have taken you more than 5 min to realize that GNU/Linux users wouldn't have been a huge percentage of your users and you could have gotten away with ignoring their advice on Flash/Javascript.

It's a good case against releasing early and asking for feedback...you have no idea if the market segment using your product is the one you will be targetting in a few months.
