And knock it off the with "buts", as in, "Thank you for clarifying, but it's not good enough..." You can say that without the "but": "Thank you for clarifying. That's very helpful. Now that I have basis to discuss your plans, I want to let you know how much I hate that..." It's not a "but" statement -- it doesn't sit in contradiction of the "thank you" -- it's an "and" statement: "Thank you for fixing problem #1 and problems #2 through #46 still exist."
The only place that "but" of contradiction makes rhetorical sense is in the latent, imaginary argument in one's head as to whether one is justified in being angry with or hating LJ [LiveJournal]. "Your clarification is a righteous behavior but insufficient to compensate, in my assessment of how much you suck, for all the other crap you've done." Or more concisely, "Yeah, but LJ still sucks for the following reason", as if the matter of debate isn't whether what LJ has done sucks, but whether LJ itself (or its staff) suck. The "but" betrays that you're really, in your heart, arguing the case of Why LJ Sucks, not What LJ Is Screwing Up This Time.

Meh. 'But' is just 'and' with a case of incongruity. That's what it is, so I don't see a problem with using it for that... though of course dark arts applications would be problematic.
