If you haven't yet registered your blog at Outpost-Earth, I would urge you to take a look at it and join the blogging minions who are registered there. It's quite an eclectic group of bloggers and it's growing by "earthly" leaps and bounds on a daily basis! I'm registered and so are many other bloggers. No feed is the same at Outpost Earth so it makes for quite an interesting and diverse representation of worldwide blogging!
For folks who really want to get their blog exposed, this is an ideal way to join a directory that is dynamic, thriving and innovative. The design itself of the site is very cool and the registration process takes less than two minutes and it's FREE!
