In case you missed it, I wrote a review of Tabatchnick Chicken Broth with Noodles and Dumplings (read: matzo balls) for HeatEatReview.com. Be sure to check it out -- the soup is delish, I promise! (Oh, and it's kosher, as well.)
Also, if you attended (or maybe you didn't?) the Nefesh B'Nefesh international bloggers conference in person or online, the list is up of all the bloggers who registered. It's seriously a list of who's who in the J-Blogosphere. Even I managed to weasel my way in!
Though, there is some debate whether there really *is* a community of Jewish bloggers. Take part in the debate, will you?
