Profile visitors list question

So Ive noticed that some people have a large number of visitors on their profile visitors list like 30 even. I thought the limit was always 10. Did they change it or what is the limit now? Just wondering.

Yes, it was recently changed to 30. Some people don't have 30 yet because it reset the recent visitors list when it was changed, so you need to get 30 visitors after the switch for it to show as 30, but that's the new upper limit.
