To Blip, RE: your sig line. Actually either usage is correct. The meaning of "I couldn't care" less is self explanatory, while "I could care less" is taken to mean: "While it is theoretically possible that I could care less, it is extremely unlikely".
I wish people would stop trying to excuse this blatant error as intentional sarcasm -- especially when they blatantly fail to speak it as such. And next time, send a PM instead of derailing someone else's thread.
that's a pretty looking gangway.
