Yes, I also use the old Reddit.

What's funny is that the old Reddit makes use of dynamic loading of content here and there the right way. The "load more comments" of the old Reddit is nice and fast. While the "continue this thread" of the new Reddit is annoying and slow.

Indeed it is; the UX/UI is also better compared to the low density of information with the new design.

The new Reddit is the best example of how shitty can get things when you use the fancy tool instead of the tools you need for the job.
