Domains are now becoming even more important as creating a blog with a unique name and domain needs to be done first. Generating links to a blog only to later change the name is a waste of time.

Also what is necessary is not only to obtain a decent registrar, domain and hosting from someone like godaddy hosting, but to also use the same brand name for a twitter account, facebook page and more.

Sites like Social Brand Search can do the searching for you. Let it check for available domains, twitter account names, facebook pages and more.
