The other one - your immediately previous post - is going in and out for me. It's been visible before, but the last time I checked my friends page the imbed was blank (though it remains visible in the permalink). [Recheck: reloading the FP, now the other imbed is visible again, but this one still isn't, either on the FP or in the permalink.]

Don't worry about it; it's probably some peculiarity of my settings and connection.
