Facebook: Bad news again

I don't like to be repetitive, so I will make this short: there is now more evidence that Facebook is struggling, confirming earlier posts from this blog. The latest stats from Nielsen Online show a significant decline in month-over-month unique visitors to Facebook in the US. According to mashable, "Facebook will unveil their re-designed user profiles shortly, which aim in part to get rid of the clutter that has loaded up Facebook since they launched their application platform."
Is this going to make a difference? Personally, I don't really think so. You can only get as far with functional improvements. If the magic is gone, then there is not much you can do.
