I want to start a blog about "graphic design" and I'm considering the following 2 options
1) Start from scratch in a newly registered domain name.
2) Buy an established domain name (4 years old, PR5, getting traffic), which is being used for something completely different to what I have in mind.
I'm tempted to go with 2, but the domain costs some good money and I would have to drop off all the current content, as it is not the subject that I want to focus on.
Also, it has an structure that is not compatible with my .htaccess file, so all the current pages indexed by Google will return a 404 error message.
In this scenario, does buying the domain provide any real value to the project? What should you do if you were in my situation? Any better option than those I've proposed?
Many thanks for your replies
