1. Between the regular job and translation/editing projects, there has just been no time (even with the snow days).
2. Since so much (actually, all) of the new work involves sitting in front of my laptop and pecking away, blogging is not as much of an outlet as it had been. When I have some time that I'm not sitting in front of the computer doing work, I'd rather read a book. Also, I have no idea how long my back will hold up if I keep hunching over the keyboard.
I wish I could say that it is temporary, or that I have nothing to write (I barely started writing up the Ezra shiurim; I've given three already, but have not gotten the chance to really write them up well). It's good to be busy, though.
