Forum users could use notifications

Just an idea. I sometimes find when I scroll way back in my activity I'll see new replies on old posts/comments. To help encourage greater awareness of replies between forum members, perhaps a sort of notification system could be developed? For the love of god don't turn the forums into Facebook... I'm just saying it would be beneficial for The Verge forum posters to be notified of all replies and comments thereby generating more traffic. Maybe it's asking too much, I dunno I couldn't make a website to save my life :p
