Cosmology has been crossing my transom. I've been getting press releases from the new online Journal of Cosmology. Below is a sample. They have a respectible team and, frankly, a kick-ass background image for their website (shown below).
And, they have a novel economic model-- a $35 submission fees, plus a $150 fee if published. Given most academic journals are free to submit but have fees upwards of $1000 to publish, it could be seen as a breakthrough in open journals. However, much as any writing gig that charges a submission fee, I am worried they are more focused on the cash than the science.
