FYI – different than many other sites – you can’t see who liked a post. The author knows who liked their post but other people don’t. (As far as I can tell, at least. EDIT: This was incorrect. See the first reply below.)

Minor exception: You can see info on someone’s user page, e.g.:

For accounts with a low number of posts, e.g. a new anonymous account with one post, you could sometimes tell who liked something.

I can see who’s liked a post that isn’t mine and isn’t in my thread, e.g., Justin Does SICP - #4 by JustinCEO

To see the likes I have to click on the number next to the like button. The screenshot was taken just now.

The default time to undo post actions (such as liking or flagging) is 10 minutes. I’m not sure why it’s so short. I’ve set it to 3 days for now.
