Display Posts - Homepage Change

I don't know if this topic is discussed/noticed before or no, I am pretty sure it isn't. 

So here is the change in the display of Top Posts on the Homepage on Indiblogger.

• Every time you refresh the page, a new category/topic loads with top posts in respective categories.
• Seems like there is  no 24-hours time limit when displaying the categorized top blogs. But, I am sure that there is some time limit to it. Renie can confirm it, I guess.
• Although categorized post don't have time-limit of 24-hour display, "The Top Post Of The Day" still seems to be considering the 24-hour limit when loaded on the fron page.

Here are the screenshots of the same. You can try refreshing the homepage - It takes around 2-3 refreshes before you can see the change of top posts being loaded with category.
