I'm always in to try new and other marketing strategies to get noticed by poeple... Thats why i have designed a nice "Coming-Soon" page for my upcoming social bookmarking tool: http://www.bookmarkwiz.com Pages like these are simply the modern version of the under construction pages. What do you guys think? I think coming-soon pages are a great way to build an email list even before the sales are starting. and as google considers domain-age as a bonus SEO wise it could be a nice benefit aswell.
