If the "MSM" (mainstream media) is biased one way or the other, it's certainly biased against the Orthodox Jewish community. Too often we're portrayed as a collection of backwaters -- by "liberal" Jewish publications as well as the secular media.
http://www.cross-currents.com/ is intended to be a serious and thoughtful blog. We'll discuss many things, but above all present our own spin on current events.
This is a group effort, with a collection of truly outstanding Orthodox writers, including media professionals, educators, editors and more.
For software, we chose WordPress. :) PHP + MySQL, plus an active development schedule and many authors of plugins (we've already implemented the AuthImage plugin to prevent comment spam)... it can't be beaten!
Please give it a look.
