The Official BSG has had a make over and been updated.
http://www.scifi.com/battlestar/ There's new cast bios/pics
http://www.scifi.com/battlestar/cast/index.php Some new Season 4 episode photos
http://www.scifi.com/battlestar/gallery/index.php?sub=season04 2 new wallpapers (Last Supper and Group photo)
http://www.scifi.com/battlestar/downloads/index.php?sub=desktops And a poster of the Last Supper pic
http://www.scifi.com/battlestar/downloads/index.php?sub=posters And on the front page there is an "Explore the photo" option on the Last Supper pic. You can zoom in on the photo and if you click on one of the characters it comes up with a little blurb about them.
EDIT: Apparently Scott Ian (from the band ANTHRAX) will be doing a BSG blog. Although it may be an April Fool's joke. The blog was posted on April 1st and one of the tags on the entry reads "April Fool's Day". So it's looking very suspicious. But anyway, he gives a shout out to Aaron on his first (and probably only, if it's a joke) blog entry.
"Obviously I will be writing about each episode this season and I also hope to have some special guests (cast members, other "celeb" BSG fans and Brent, Jason and Eric my buddies that are as insane as me about the show) be a part of this as well. Yes, I'm talking to you Chief."Source:
