I humbly disagree. I actually kind of like this strategy. I do see your point but you could avoid that issue by thrn having a page "were sorry- we haven't finished development we plan to be launching XXXX date." You could even take it as far as to give them a free coupon code to guarantee a user base when you start. Additionally you get to gauge what/ how much people would pay. Maybe having a changing price, you could gain one of the most important pieces of information before launching! Lastly, this wouldn't be a huge issue because it is a landing page. You are not promoting it to your user base- the people happening on it are doing so naturally and therefore arguably the truest clients. If your product is both unique and something people need (vs something people want) and if its getting hits without any work- then you have a monopoly of sorts and people will definately be retuning either way. This is no joke one of the most brilliant suggestions I've heard. Please hit me up at avi@trustable.com id love to talk to you!
