Allow me to explain (my) hate.
I saw this while browsing from my phone at a coffee shop and thought to myself, "hey, bookmarks are a pain in the ass, let's have a look"
The product could be awesome, but it took so long to get to the point that I gave up, and when I did, my history was completely full of worthless slides that it was easier to close the tab than go back.
This presentation is a great example of bad design. It wastes the readers time by failing to convey useful information quickly. I am forced to sit through a seemingly endless stream of totally worthless transitions and effects.
A presentation like this reflects very badly on the product it represents. It assumes that it is more important than me, the person on the other end of the keyboard.
