A big J-Blog welcome to Balashon, the "Hebrew language detective" (if you can't tell, that's a double pun in modern Hebrew).
Dave, an amateur linguist, covers a topic close to my heart: the origins of words and phrases in Hebrew and other Jewish tongues. Take a look at his great list of sidebar links! (He could use a blogroll, though. Hint, hint.)
I hope he joins the campaign to save Hebrew's vowels!
