What are you looking @?
Most of us the world over recognise the @ symbol. Once a seldom used key on the typewriter, @ is now the top dog of electronic communication, thanks to emailing and tweeting. Prior to this, it was used to represent quantities of something. For example, Peter bought 4 oranges @ 30 pence each. Its origin is vague but it is believed to have been used by medieval monks looking to save time when transcribing long manuscripts containing the French word à – meaning at – by looping the nib of the pen around the 'a' in one sweep. Later, @ was used by traders as a short cut for the word amphora. Large clay jars were used to ship wine, spices and grain and amphora was a unit of measurement that would determine the amount these jars held. This could also explain why it became common to use @ to mean 'at the rate of' in relation to quantities.
A status symbol.
A symbol can define how you present yourself to your customers, influencing the vibe you want to portray. So next time you are looking to use a symbol, don't just pick one because it was the first you came to, think about what you're designing, who it's for and then which symbol fits best aesthetically.
