Jack invited J-bloggers to submit their own favorite posts for the ultimate J-blogosphere round-up, and the results are now available. I was not familiar with most of the posts, so this is very welcome. Somebody could also do a best of Haveil Havalim or a round-up of the all-time best posts about Judaism and Israel by non-J-blogs. And, of course, what Greatest Hits is not followed by a Greatest Hits Vol. 2?
