Way back in the mists of time (2009), it was OK to only have a website if you wanted to have a web presence.
But now it is becoming more and more important to have a Facebook profile, a Facebook Brand Page, a Twitter profile, a LinkedIn account, a YouTube account, etc, etc.
If you own your own domain name it is good idea to use sub-domains to create really cool and clean web addresses.
facebook.com/briancurrin is much cooler than, for example:
However Facebook.BrianCurrin.com is even cooler, very clean and great for printing on business cards, flyers and other advertising and branding material.
This sub-domain idea can be used for almost anything, such as:
… and so on and so forth.
You might wonder why I haven’t included “www.” as a prefix for these addresses. This is not really necessary in modern web browsers anymore, but for printing purposes you might want to include it. Even better, though it is a bit ugly, is the “http://” prefix.
And capitalization is not really an issue nowadays either, so www.Facebook.BrianCurrin.com works perfectly and it looks much better from a branding point-of-view.
