(You found me!--heh heh...I sorta know what you mean and agree.  There's the relationship between the user and the site, how does the user negotiate their own input, their comments etc...--a good example--maybe slightly sideways, but Trond Ove put up a diary yesterday with two hour+plus videos.  I want to watch them and then comment, but that'll take a few days, by which time the diary will be gone from the lists...so if Trond Ove had the easiest possible way of knowing that his diary had received a new comment...and ditto for comments...which is why I snuck this one in here--er, something something!)
