a friend asked me what domain they should register for their new blog and gave some examples. do you think they should register a domain in their name e.g. firstname-secondname(dot)com or related to the topic e.g. topicname-blog(dot)com ?
If your friend is writing for his own then he must register a domain by his name. But if he is writing an content for other topic like tech, medical, insurance, then he must choose a domain according to topic.
