Money should be nearing the end of its beta, so what should the logo be for Money?
I'm kinda partial to whiskey and nickels. Seriously though, since money has international followers it doesn't make sense to use the US dollar sign or any other currency sign. It also doesn't make sense to use green colors predominantly in the design just because that is the color of money in the US.
Since government currencies come and go, I would prefer to incorporate the most predominant form of money for the last 5,000 years: gold and silver.
Probably some icon displaying coins and paper banknotes. And maybe added to that some chart charts (symbolizing stock, etc. investment). Maybe a piggy bank too?
I would try to avoid going to $$ signs - I know it's recognizable and most of the topics would end up related to dollars and US matters anyway, but if we could have something more generic it'd be nice.
The logo for Money should be a a large, green "dollar sign":
Although some say the above sign isn't international enough, it's definitely internationally recognizable. In addition that same symbol not only used in the USA. It is also used in Canada and Australia + NZ. That's 2 entire continents!
Interestingly, the $ sign has a Spanish origin (originally called the peso sign)
How about very old currency? I linked to persian coins, but anything would do
Another brainstorm (that I like less) would be to incorporate modern currency symbols and the old coins together.
This is just an idea and I don't have any picture ready to show this but here goes: A picture of a hand shake (symbolizes communication between people). Then a glowing bulb above the handshake which is made up of a currency note instead of transparent glass..(symbolizes ideas that are generated as a result of information exchange between people).
When I think of a design for this site, I tend to think of something that is reminiscent of a brokerage website or retirement site - clean, crisp, straight vertical and horizontal lines, and lots of white with one or two other colors in varying shades.
That said, I am somewhat partial to the idea of moneybags in the logo marked with different major currency symbols. There's nothing about them that's clean and crisp, but I think it conveys the idea that getting good information and advice here will help you get and keep a bit more money.
