I play on and off 360. When I'm on it, I neglect a majority of friends here. I've been using it the past few days, and will likely take a week or more break.
Also, my friendlists is constantly full. I only speak to maybe 1/4 of them anymore, but the other 3/4 were good friends and I feel like I'd regret to just remove them... Ah, memories of those friends...
