YSK that you can view the old-style reddit profile page for any user by clicking the three dots at the top and then selecting "overview"

I've yet to find anyone who likes the new-style reddit profile pages. They're ugly, hard to read, and objectively worse than the old-style pages. If you prefer the old layout then you can select the "overview" option which is hidden away in the menu at the top.

For example, this is a test account I use for moderating, which has the new layout: /u/asmr_mod_test
