I am pretty sure the only way to send feedback to the Chrome team, other than the Chromium bug tracker (which is pretty much the same people), is to send feedback from within Chrome.
Obviously, I don't have Chrome, since my issue is them pestering me to install Chrome. Which I'm not going to do.
On the other hand, if Google wants to prevent their reputation from sinking to the level of "install the Ask Toolbar", one of the Googlers on the Chromium bug tracker will see that it is dealt with.
Just to clarify, the product you should be reporting this on is Google Search, or whatever site you're trying to use the browser on that's giving you the annoying reminder. Not the browser itself.
