Yes, I know, everyone hates the Facebook ticker. Well, not everyone. A friend asked if I could help figure out how to show the Facebook ticker on her account. Googling it only seems to show anti-ticker and “how to remove” it posts. So after digging around and checking a few friends accounts, the conclusion is: having less than 100 friends is the most likely reason you aren’t seeing the ticker. There is no option to turn it on, but there is an option to hide it.
If you’re close to 100, try adding a few friends and see if that helps. If you aren’t close to 100, you may be out of luck. I’ve heard of some people over 100 who don’t have the ticker, but having over 100 friends is your best bet.
