Action Streams I just got through installing the Action Streams plugin.  Needless to say, it didn't go as smoothly as I hoped, but it's finally done.  Had to hack together a widget for the actual Action Stream itself (showing on my main page as "Other Stuff" at the bottom of the right pane), though the template-installed "Find Authors Elsewhere" widget worked fine.

Of course, when I installed the template, it completely destroyed all my layout, and in fact wasn't even listing my last blog entries either.  So...twenty minutes of restoring the templates to the default, then setting all my styles and layouts back to how I had them, and now it seems to be working.  We'll see what happens - it doesn't seem to have caught my Facebook status update, so I'm guessing it's probably not 100% functional at this point.  We'll just have to see what happens!
