Mark Zuckerberg giveth and he taketh away. Facebook users are reporting today that they can no longer see the real-time “Ticker” that describes their friends’ activities on the right side of the Facebook home page.

TechCrunch reported that the disappearance of the ticker is widespread but that it should return online soon. And you can see from the blank space at right, the ticker is gone from my Home Page as well. Sob.

It isn’t clear why the ticker disappeared today but we’ve got a query in to Facebook. Hopefully it’s something like maintenance or a bug fix. One user said a friend at Facebook told him that it would be back online soon.

The ticker is very important to Facebook’s developers because it shows what people are doing. That helps apps spread, since people are likely to click on a lot of the live links on the ticker if they see their friends there. As such, the ticker is prime real estate and helps apps go viral.

If  it were gone, app makers would have to spend a lot more money advertising their apps in order to get people to notice them. TechCrunch said that reports started appearing on Twitter at about 9 pm on Saturday, June 30 about the missing tickers.
