Losing all of the information on TAC would be tragic.
Even more tragic would be forgetting one of the fundamental rules that has allowed this site to become what it was (and hopefully will be gain). I was disappointed to see how quickly some people seemed to forget.
No politics.
Now, this is just my view. I'm not an admin. But I've been on TAC since well before the complete wipe-out in 2007 - I think about 2003-2005. Just remember that every time you post a political comment, there are probably 50% of people - yes, even here - who disagree with you vehemently. Any political comment here is essentially trolling, and whatever political opinion you post, no matter how sure you are that it's true, or obvious, or surely must be held by everybody else, half of the people reading it are going to think you are an idiot for holding that opinion, and the other half are going to think that you are a jerk for posting it here.
There are lots of other places where you can talk politics where you won't be damaging something special.
