It's a great feature to be able to look up discussions by game, but other than that Giant Bomb forums have always been rather useless. They are effective at discouraging any exchange and mainly serve as a dumping ground for comments like "<>".
Why can't I subscribe to discussions, in order to easily find them again?
Why am I not notified automatically when someone replies to a topic, in which I participated?
The @reply feature at least gives a way to illicit a response, but it is absurd and unnecessary since forum discussions are public. Every reply to a topic addresses everyone able to comprehend it. Meaning that I would have to address everyone in that way @every @single @one for every comment I post. I could also just quote someone if I wanted to single them out.
I love discussions, so I've seen plenty of forums collapse under the unmanageable weight of their popularity and the trolls they attract. Still, forums are a community feature that works, they are a reason to visit a website and visit it frequently! As opposed to every other community initiative like fake "social network" features, or "gamification", user participation, "crowdsourcing", "likes" or Twitter integration; just to name a few.
