I want to startup a blog with the tagline 'Between skepticism and belief' that provides an objective and evidence based perspective on alternative medicine (acupressure, yoga etc.) and various popular self-help techniques (the secret, spirituality, meditation, NLP). I thought that empiric spirit would be a cachy name for it.
If you like it, go for it. Blogging takes a lot of energy and commitment, so go with a name that resonates with you first and foremost - you want it to be a place you really enjoy writing. That said, it can be helpful to 'brand' something in a way that's easy to remember - easy to spell, easy to pronounce. You can test that by simply asking people to spell it when you say it to them, or by showing them the name and asking them to say it. People may have trouble with "empiric".
