I was getting them before, but now I'm not.
Mine is checked too and you quoted me and I didn't get a notification of the notification*.
* no notification in that notification section (with PMs, friend requests, picture comments and quote notifications) on every site, but an actual notification on the quote notification's page.
I've seen it take anywhere from 10 minutes to 30-60 minutes before the notification will show I've been quoted after a quote has been made.
