Hmm. Thinking back to the desired slider interface, you could put a
good number of radio buttons horizontally across a page. The voter
could click in the desired range. Something like:
Very Bad Neutral Very Good
O O O O O O O O O O O O O O O O O
It wouldn't slide (ie, you couldn't hold down the mouse button, and drag
between buttons), but it would be visually close.
I don't know how 'heavy' this approach would be, in terms of page size.

I think MSIE works like NN. But I'm far from being an expert.

I think so. But a drop-down wouldn't suck, it just wouldn't be the
best. Not saying that I know radio buttons would be better, but it's an
idea.

I didn't explain my idea very clearly, sorry. I figured the server
could take the [1,10] votes, and map them to the [-100,100] range. The
mapping could even be non-linear, but that's probably overkill.
BUT, like Dan said, avoid the numbers altogether. The horizontal UI
thingy allows you to only use general labels.

Good point.

If we're talking about Freshman Chemistry exam scores, 0 is bad. Then
again, anything less than 90 is 'bad', in that case.
That may be a problem -- people looking at message scores may interpret
near-0 scores as bad, rather than neutral. I think that is an issue to
resolve with user education, via clear labeling.

Agreed.

Not necessarily. It's logical, but people are used to things being
rated starting at 0. Then again, people are not used to having combined
'good' and 'bad' ratings. Usually, ratings indicate *either* how 'good'
or 'bad' something is, not both.

And the midpoint. Establishing that mid-range is a neutral stance is an
important feature of the system.
But I think Dan is right - avoid numbers altogether. And avoiding
numbers also means that voters would have less trouble accepting the
score they see after they cast their vote. Since the entire
votes->score transformation becomes a magic black box, they don't have
to worry about why casting +100 as the first vote turns into a score of
only 50. Provide the details (somewhere) for anyone who wants to read
it, but don't put it on the voting page.
