quick thoughts:
loads real fast, that's great
at first (first two seconds) I'd think that it's one those 2 or 3 page salesletters that do nothing but promote their own product. then I read down and I see "free...newsletter" and I stay (I do subscribe to ezines).
it does grab my attention
it's very clean and focused

if it helps any I'll subscribe to the ezine and send you my 2 cents

also, a site does probably the best job of promoting their ezine is wilsonweb.com it promotes it's ezine at every opportunity, but not in an annoying way. and it's always giving away something "free", or "in addition to" for signing up

good work
