it's sort of appalling as an LJ support person how many people didn't realize it was possible on LJ.

For some of us, it's sort of appalling how long we didn't realize it was there. It makes us feel terribly inobservant. :-)

I think it might be a good idea to at the very least have some sort of list somewhere of all the nifty bells and whistles, both on LJ and DW, because clearly, lots of users are still missing this stuff.

Comms like the newly formed dw_nifty will be of a help too, of course, but something more official would probably be good, too.
