Okay, after some thought, I do like the idea of the change but I'm not a fan of the new browse page as it currently stands. I have 2 complaints about it.
first: I hate hovering over a torrent and seeing something that just doesn't turn me on or that I find unsettling, like open areses. I then instantly unhover. At least with the normal "browse/search", there are sub category thumbs or descriptions which might give you some warning about the content you might see. And then it's my fault for taking the risk. With this new browse, everything is instantly dumped right in your face, big dicks, small dicks, daddies and sons, fisting, interracial etc… Having what you don't like unchecked in your profile doesn't always mean you won't see it. I'm not talking about the recent bug fix, but the fact that videos still appear under wrong categories or are hard to place under just one category and so have their "main" category set as say.. "hunks" or "bareback" but that contains "twinks" and "interracial". Whilst I understand that it's hard to decide which category something should belong in, the browse page forces you to view it all.
second: forcing a user to download so many images is never a good idea, it's bad internet etiquette and some users may have slow connections, download limits etc...
I understand where the changes are coming from but I think this first draft needs some work, if you want some sort of "recent upload" thumbnail preview, I think it might work better with fewer images, i.e the last 10 uploaded torrents (excluding ones from categories that are unchecked), and in some sort of carousel rather than a screen dump (it just looks like a bunch of random images). That way it could also be contained in a small "banner" like module and it would be easier on the eyes and the bandwidth. However the problem still remains of seeing things someone might not like. Is there a way to take into account the "sub categories" for each torrent, and filter the torrent if any of these also match anything unchecked in the profile. For example, I have "daddies and sons" unchecked but I'm still seeing torrents that have this as a sub category. It might also help to rename it from "browse" to something like "browse images" or "browse thumbnails" or "browse torrent images".
Apologies if any of this has been addressed, as it took a while to write!
