Comix 411 - Now part of a larger entity called Gear Live. However, the comic page hasn't been updated in over four years.
Francis Manapul's Art Journal 2.0 - This was abandoned in 2011. Francis can be found on Twitter and Tumblr.
The Kid's Comic Book Reviews - They made a "we've moved!" announcement in 2011. The site to which they moved is gone. They were going strong for a couple years though (08-09).
I Believe In Bat-Mite - Almost the same story as the above Kid. Hot'n'heavy in 08-09 and dead by 2011.
CHESTERFEST - CB Cebulski's been busy since this blog stopped in 2011. He's now Editor-In-Chief of a small publishing outfit called "Marvel".
Ordster's Random Thoughts - Jerry Ordway has been blogging here intermittently since 2007, but only one post in the past few years (last August).
The Defenders Fansite - To be honest, I'm a little surprised to see a recent post (May). They've gone from a weekly to a monthly blog schedule.
Big Glee! The Albert Bryan Bigley Archives - Al Bigley has gone from a daily to a monthly, but he's still going, bless 'em.
Retroactive Continuity Redux - Well, his dog died, and so did his Twitter feed: "Evidently my Twitter feed no longer works. I shall investigate it in the timely manner to which you've all become accustomed." Just all gone now.
Brainfreeze: Comic Love - I don't know. Is this it now? Probably not...
I've been visiting old comic blogs to see what's still alive and where everybody went. Some are still going, some are dead dead dead and some have evolved into a Big Deal. Most of the links are Twitters.
I've been using Comicblogupdates (CBU) and Update-A-Tron (UAT) to facilitate this project. (Quite a few of the links on these two sites rely on RSS/feeds. Some sites are still there; the provided link is just defunct)
