You must be using a different reddit website, the one I know is horrible. It's slow, it's buggy, videos don't always work without a refresh after waiting 10 seconds to be able to click play. The UI is all wrong:

for example, you open the comments of a post, it opens a faux-modal with a X button. You tap it, it closes the post but opens the subreddit. It doesn't go back to where you were.

Another example is how to collapse a thread on the comments you need to press the empty space beside the username?!?!

It's so slow and wrong that I've built my own front-end, but it's virtually impossible to load reddit videos correctly...
