I’ve had it for years on a site that gets 60,000 unique visitors a month. No one ever uses it. Have you? I have used it once or twice on a news site. I’d rank it at the bottom in terms of selling strategies.
Depends on what it is. I have used this on youtube quite a few times. Its easier than opening up my email client and copying the url into the email.
Rob – You might look at wufoo for something like this.
