PsyBlog posted about some research on the use of emoticons & capitalisation in emails and:
“They found that, sure enough, using correct capitalisation and emoticons tended to make a better impression on readers. The reader’s personality also influenced how emoticons and capitalisation were perceived. Readers high in both extroversion and emotional stability were likely to rate sender’s emails as more likeable if they had correct capitalisation. As for emoticons, readers higher in emotional stability were likely to rate sender’s emails more likeable if they used emoticons.”
At last there is some evidence that supports my personal opinion!

Thought that was really interesting, thanks for the tip, Kate. Now where’s the study on use of lolcats in business communication? 😉
