Biggest mistakes made by web masters

Hi, I'm Scott Nailon. I built my first website using notepad on my buggy Osbourne Pentium 133 (Windows 98) computer back in 1998. I have been running my own business since 2006 with a specialty in web since 2008. Most of these blogs are my own, if they are written by someone else I will have attributed that person at the end of the article. Thanks for reading!
