Everybody else is posting thoughts about Doppelganger, so why can't I?

I was worried that I wouldn't actually like the episode, after so many people who saw it early have been gushing about it. But it was great. I laughed out loud at least twice, and I got fodder for three different Rodney pairings (as if I needed it).  I really hope the rest of the season is this good. (Although the previews for next week suck hard.)

( Thoughtful analysis ... NOT!  )

Grrr!

Sometime yesterday evening, Livejournal stopped sending replies to my posts and comments to my email. Does anyone know what I need to do to get this fixed?
