No, I did not die.
I'm still spending most of my on-line social time on Facebook. And I'm still wrestling with how to have all of my activity show up in one place. Like most people care. :-)
The best I can do right now is FriendFeed. You can find me there and see most every piddly detail of my on-line activity except for Facebook. Apparently the nitwits at FB don't think it's worth it to have individual users' activity available via standard means of sharing—and come to think of it, maybe they're right. So if you really want to see what I'm doing on Facebook, you can look me up directly on there.
I like FriendFeed because it also works in the other direction, letting me group friends' public, on-line activity feeds together in a logical way. Friends don't even have to be FriendFeed users, but it makes things nicer if they are. (hint) ;-)
FriendFeed is still not the holy grail, though (to me). As mentioned, Facebook doesn't play well with it, and there's still no way to read friends-only things (like semi-private posts here on LiveJournal) without checking individual sites. Maybe Flock is good at this, but I wouldn't know because I haven't tried it, and since it is a browser and not a website, it must be installed before it can be used.
So, bottom line: find me on Facebook to see what I'm doing on Facebook, look at my FriendFeed feed to see everything else (everything that can be made public, anyway).
And I may yet get back into making big posts one of these days. It may or may not be here on LJ, but it will be made known here.
