Sometimes, you aren't looking to build a web presence at all. It's not about the future, it's about right now. If you are just needing to launch a site for a special event or for a limited time, Site by Nite is ideal.
You don't want to sink a lot of money into site development or even for someone to manage the site. If your need is very short-term, you also certainly don't want to lock yourself into a year of web hosting services.
Site by Nite will allow you to quickly select a site design that meets your needs, allowing you to focus valuable time and energy on loading your site with your content and getting it launched. Anyone can run through the video tutorials in a matter of minutes and have enough information to to start creating their site.
Especially when the clock is ticking and you need to get a site up quickly, you need to cut the time needed to develop a site out of the equation. Reality is, websites always take longer to develop than expected. Creating content may be a big enough hurdle without having to wait for a designer to present you with concepts, make modifications, and then start to build whichever design you picked. Site by Nite quickly moves you past the design stage to the important step of content creation.
And since you are in control, you can create and launch pages on the fly, so no waiting in a designer's queue to get to your project. The quarterly billing is ideal for this too, as it covers you for the month before, during, and after your event.
You'll of course have your domain name, so you can always turn something that started out as temporary into a web presence if you need to, and email to that account can continue to be monitored or forwarded to another account, depending on your needs.
