Yes, the use of color does affect the download speed of a website.
Websites with color download more slowly than websites without color.
The hexidecimal values used to specify colors can contribute several
additional bytes to HTML and CSS files. But this difference is

It shouldn't make any difference -- the choice of color does not

To clarify, the selection of one color over another doesn't affect

Micheal,
That's a good question. As far as solid research goes, I haven't
come across it, though I'll keep my eyes open.
Wearing my user hat, if I saw 0 stars/0 reviews everywhere, I would
probably get the impression that this site doesn't have a
community.
I'm having a similar challenge at
Another option is to have somebody go through and review each item
once. I know it seems disingenuous, but frankly it's the solution most
often used. Hiding the ratings until you have one results in UI
inconsistency. The problem you're having has to do with user
participation -- sometimes
As Adrian mentions, seeding is a bit unethical, as the reviews aren't
authentic. (keeping reviews authentic is an ongoing problem all the
time, however)
Another idea is to reward first reviewing behavior.
So, give people a special badge on their profile when they review an
item first.
As a user, I typically dont go and start rating - depending on my
mood, time available, usefulness of the content etc on product pages.
Also I have seen many users who do a random rating just to
complete a process without giving away the actual feel/usefulness of
the product.
The other way I can

that black text on a white background is easier to read than white on
black. Anything in between the two would be a judgement call.

With regards to hiding ratings:
Zappos, for instance, hides the ratings on the search results page,
until the shoe has been rated.

be consistent.

Not sure I like the zappos approach. Visually, i would prefer to have
the ratings even if they're blank. For consistency's sake ;-) (If
consistency isn't desired for its own sake, then for what else?) Now
that's just a visual argument. In terms of what it indicates, the lack
