Having a domain name can really establish your online presence. It helps you establish your presence and gives you a foothold in the untamed territory that is the internet.
For my Domain name I would choose dannyblaxon.net or .com. I would only do that because that has become my online identity. Many people may not know me but dannyblaxon is my own creation and I will not give that up. It is the name I use for my youtube videos and my twitter handle so I will just continue the trend and expand the dannyblaxon name on the internet.
