Identifier, first impression, signage, brand, arbitrary label...just remember, not what they call you but what you answer to
In case you haven't noticed the change of URL (and why should you, what with running silent for so long), an explanation might be in order. The name is the same, so is the basic url, but the domain name redirect url is gone. That url matched the blog name. I bought domain name to be diplomatic knowing a metaphoric kick in the shins is all it would get me. When time came to renew I didn't because money is too tight to spend on empty diplomacy.
What difference will it make? Depends. None, I hope. Any reader, whether angry, upset, confused or just curious, are welcome to come over here and comment or ask questions.
