Requested feature overview description.
Get rid of all the "Popular" sections.

Possibly bring up "advanced" search page, similar to something like google. This would then still allow users to search this content with ease without knowing how to use metatags to full extend. I'm certain this can teach users to use search function better and many find it easier to use mouse driven interface.

Or alternatively simply forward the thing to order:score date:today search directly instead.

Why would it be useful?
This part of the site is plain bad.

Because the page is reset at the exact time every day, this means there are users and artists who deliberately try to aim to this time window to get their posts bumped higher up. This to me has always felt like taking advantage of the system.

Only aspect what determines popularity is the amount of votes. Favorites, comments, views or anything else doesn't contribute to the post being popular. Because of this, the page becomes order:score date:* where we come to full list of issues:

• There's 32 results in total. There's no button to see more or to get to page with search results. That means that if the post was 33th, then tough luck you aren't seeing it in any way.
• No way to refine the aspects of the page to what you want or don't want. Have female blacklisted? Even if Jasonafex did say that majority here are gay and that's why everyone got mad at vagina, get ready to have 99% of the popular page be just box with "blacklisted" written on it, because most popular stuff almost all the time is solo females with genitalia focus. (Example of popular page on 26.5. with only "female" on my blacklist: https://puu.sh/Ats1E/2e6a39b01c.png)
• Extremely hard to get to specific dates. There is forward/back buttons, but if you wanted to see what was popular week ago, you'll have to click back 7 times, on top of that there's no ranges outside set day, week or month (where with advanced search if it had similar search to something like comment search, would have clickable calendar with your local time format: https://puu.sh/AtsK6/662cf2cdd7.png)
• If it's less cluttered interface that someone wants, there's link to "Mobile" which looks similar.

Only reason why I can see this page being useful if the user is too lazy to learn how site works and wants to have one click solution, instead of three click or creating their own one click solution in form of browser bookmark.

What part(s) of the site page(s) are affected?
