It's hard to imagine, but there are still companies that don't have a website.
The effort/cost of getting one designed, frustrations with many web designers (or people/companies that claim to be web designers), the list goes on and on.
Microsites are also growing in popularity. These are dedicated, small websites for a specific product, project or purpose.
Here's a great teaser video for a Microsoft microsite (say that quickly 10 times)
So you want a website, or want to create a microsite, and you don't know where to start?
Paraphrasing Nike, "Just Do It."
There's a new tool that lets you set up a website online, create the content online and even provides hosting, all FREE--Synthasite. You go to their website, create an account (name and email are all you need), and start creating. You can use their subdomain (greggssite.synthasite.com),r register a domain and have it redirect to the site you've built, or download all the files and put them onto your own website host. It's slick. It's quick. What are you waiting for?
