Why would anyone in their right mind switch from a nice .com to the less desirable .net domain extension? Well I came up with what I think is a good reason. Since Regex Hero is very specialized towards .NET regular expressions, I thought it'd be good for my search engine placement if I make the switch. Google will put fairly heavy emphasis on the domain itself and even the extension when considering keyword relevance. So if you search for "ASP.NET" you'll find www.asp.net is the first result. Likewise, I'm guessing that eventually my search engine placement for "regex .net" will be quite good. Of course I still own regexhero.com and if you go there you'll be instantly redirected to regexhero.net , so this switch shouldn't cause any broken links.
