This is a really cool idea, and I like the newsletter layout. My only critique is that it's not immediately clear what the site is for, and the paragraph that spells it out (top-left), is not in a position that I would tend to read first (I went logo then skim "Art of the Propogator" quote). It may be worth considering giving that paragraph a more prominent place, at least for the first few editions (or maybe just the web version, since presumably people know why they gave you their email address).
