When I was planning to start a new domain on WordPress the first few names which came into my mind was with keyword WordPress. I was about to buy the domain name but luckily while talking to one of my blogger friends, told me about the issues with using WordPress in the top-level domain name.
After little research I landed into the page from WordPress which clearly says
For various reasons related to our WordPress trademark, we ask if you’re going to start a site about WordPress or related to it that you not use “WordPress” in the domain name. Try using “wp” instead, or another variation. We’re not lawyers, but very good ones tell us we have to do this to preserve our trademark. Also many users have told us they find it confusing.
To be honest I second their opinion of not letting anyone using WordPress in top-level domain. Though users are free to use wordpress in sub domain. For example
WordPress.shoutmeloud.com and so on.
I was reading a post on WPgarage which faced the similar issue as they had WordPress in primary domain name , but later they moved to WPgarage from WordPressgarage.
Even I was confused before selecting the name for my WordPress dedicated blog and after all this confusion I bought domain name WPSutra for WordPresss tutorials and themes.
On the other note, if you buy a domain name with WordPress as word, you might not face any problem in beginning but later get ready for mail from Automattic company.
In case you have any existing domain name with WordPress as domain name, move it to wp equivalent domain name. For ex : WordPress Sutra to WPSutra . For this you need to do a 301 perma redirection.
Do let us know your thought about Matt preserving its brand name by not allowing WordPress fans to use WordPress as key in domain name?
