A great idea is essential for any worthwhile endeavour. I thought it would be a great idea to have a domain in my personal name as the web just keeps growing and growing. In most instances it will be difficult to purchase your personal domain (ex: yourname.com) especially if you have a common name. It would certainly be worth your while to try for it as your domain will be your personal business card for the rest of your life if you want it to be. If dot com is not available, there are many other suffixes
that might work for you. The cost for a domain is minimal at $10-$12 a year and your website has to be hosted somewhere so that search engines can find you. Hosting is cheap at about $5/month and I recommend SiteGround for your hosting needs. Why not give it a try.
