Cool: Speed, better organization/searching.
 
Lame: No favorites.  
Mostly because sometimes I just want to upvote images, and sometimes I want to archive them.

Site’s good in general. Speedy, pretty and easy to browse. Genuinely though, I miss the assholes. I think the problem here is that you need an account to comment. That’s probably why there’s so little discussion per picture. PB was the fandom in its purest, most unrefined state. Some people didn’t like it, but I enjoyed watching that stuff play out.

Most Favorite: The speed, the grid view, the preview handling on image pages, the fallback sans JavaScript, the images having (mostly) centralized URLs.
 
Least Favorite: Overriding the arrow keys. That’s why I usually leave it forbidden in NoScript.

It’s under Lists, where we also show the overall top upvoted, and the weekly top upvoted, top commented top and other things.
 
Guess I’ll add to the list that it should be a separate, more identifiable thing thing

We have it?! But how is it accessible from the front page?

The comments section in Ponibooru showed the comments made on a pic as the name suggests. Other examples of this can be found on 20pc.org or e621. Whenever someone makes a comment on a picture in Ponibooru, the pic would be bumped to the front page of the comments section for others to see, which allowed even more views for that pic. This allowed discussions to occur more easily on certain pics and for longer periods of time, as others would see the discussion and join in as well. I think that if this feature gets implemented into Derpibooru, it could help increase the amount of people visiting here a lot.

That’s a known bug on the to-fix list. The image on the page itself, as well as the one you get to with the “View” button, should always have the proper tags and number.

The End wasn't The End - Found a new home after the great exodus of 2012

I have to change my least favorite.
 
When I try to save an image, the proposed file name doesn’t reflect the updated tags, and it’s even the original file name if the image isn’t optimized yet.  
And this sucks.

Favourite: Faster than Ponibooru, cute ponies.

i actually change my dislike.  
the fact that i dont use grimdark or grotesque hidden tags, but people put explicit and questionable on the same fucking picture so i dont see it anyway.

the only thing I don’t like is that there is no tag for your upvotes like the “favourited_by:”-tag on ponibooru so I can’t look through my upvotes with only one or two specific tags, to find pics that I like more easily.

Likes: images the easier use of tag filters and voting system…
 
Dislike: the morons that can’t take 10 seconds to filter out tags they don’t like, and still b**** and complain.

Most: The layout, while reletively simple, is still more attractive than ponibooru’s and while we’re missing some of the better features Poni had, what we have here seems a bit more polished.
 
Least: That user with the creepy anal fetish, really don’t like him.
