zunzun.com is gone due to its owner, James Phillips, going partially blind
and therefore being unable to maintain it. For those who never used
zunzun.com (probably everyone reading this) it let you paste a bunch of
rows of text, each containing two (or even 3) numbers, into a text box, and
then it provided a best function fit with full statistics. I used it a
_lot_ because it was one of the two most useful online tools I've ever
found: the most useful being Calchemy, a units calculator that does
automatic solving by dimensional analysis
http://www.testardi.com/rich/calchemy2/, and even it has been degraded
from what it once was.
People just don't seem to 'get' really good tools.
