I discovered GiantBomb about a year ago and subscribed only a few months later. What Drew me to the site was how professional and mature the team was, not to mention the great quality of the content. Yet despite this professionalism they did not take themselves too seriously, unlike other gaming centric sites *couch*Kotaku*cough* and also, they were not crass or juvenile, the polar opposite of Destructoid.
I only started heavily visiting the site shortly before Ryan passed away and honestly, I didn't know how to handle it. But since then I have devoured Quick Looks, Endurance Runs and all the other craziness of GB. In doing so I see that these guys really care about what they do and what's more, they care about the people they are providing this content for, non-subscribers and subscribers alike.
I am a bit of a lurker but from what I can tell the GiantBomb community is one of the best on the net. I struggle with severe depression and GB has been there a lot for me, as silly as that may seem. In many ways I am living vicariously though this site but that's OK with me. All I hope is that Jeff, Drew, Patrick, Vinny, Brad and Rorie continue to do a great job.
