....and I had no clue what it was until I checked the nav bar, and saw it was a facebook update... wow, I thought, maybe they fixed the facebook app in the background without forcing me to update. Haven't seen the blue light since, and it has been 2 days and 7-9 notifications later. Any idea when they will fix the facebook app? Or better yet, any idea how I got it to light up once randomly? It was somebody posting a comment on my wall post fyi (and the notifications still don't refresh in the app itself). Also, why can't I view linked youtube videos from other peoples comments? Obviously the droid can use youtube, so it seems odd that they wouldn't let you watch posted videos.
