It's perfect for your friends and family who have never seen the series to dip in and learn about the show, the characters, the plot arcs. There is a glossary, awesome posters, desktops, and IM icons for download. There also are links to the full 44 minute recap show narrated by Mary McDonnell's Laura Roslin.
Also, If Magazine has a fairly spoiler free review of the two hour season debut of BSG, reviewed by Sean Elliot.
