I'm plodding through a thick bout of ennui at the moment and that prompted me to dig up this thread again
When I'm bored, that's when I visit other sites. These days, it's occasionally the Book of Face to see what interesting things are going on in the lives of my longtime friends. Even less frequently than that (and only *slightly* more frequently than before I was on FB), I'll go over to my Yahoo Groups account and review all the groups I'm part of, see if there are any new files or whatnot...when not (and that's mostly the case these days) I can purge it. That said, I added a lot of groups to my account back in the heyday...there's probably 100 pages still to go through, and I may not even get rid of all of them on the off chance of seeing something new. But no matter what it's a productive use of my time: if I'm really, truly bored then I'll usually end up deleting most of the groups I visit, which nicely trims the account down.
If you're looking for something to preoccupy yourself, I'll suggest visiting Hulu and checking out the alphabetical listing of TV series they have. There's actually quite a lot of freely-available content there, both new and old shows and even some foreign ones (they've rearranged their categories, but at one point they had a devoted "Korean Drama" section, for instance...I don't know if they were subbed/dubbed, but they were there). I like to spend a lazy afternoon just browsing through (there's an extensive collection, so it takes a while) to see if anything strikes my fancy and make note for when I am moved to see something different.
