The Great Friends List Purge of '07
I feel bad.
I just did some MASSIVE house cleaning of my Live friends list -- 96 people down to 28. I imagine that there will be some hurt feelings, especially within my clan, but I felt that my FL had gotten out of hand. Whenever I'd go to play a game, I was just getting constant notifications that "<gamertag> is online". Also, it gets hard being spammed with invites all the time. Sure, I know I can turn notifications off, but there have been times I've forgotten about turning them off and I've missed invites that I wanted.
From a clan perspective, I felt that if I had a handful of clan members, I always knew that I could find my way into a game with all the other people I had deleted.
I expect that I'll add a number of people back to my list once CoD4 comes out, but until then -- if you find that I'm not on your FL, don't take it personally. I still hope to see you online.
