This press release from AskOxford notes the changes in hyphen usage in our language:

For example, E-MAILS have become EMAILS and we are twice as likely to COOPERATE than CO-OPERATE. We are now ONLINE not ON-LINE.

Note also that among the new words/definitions added to the OED are some that might be of interest to Kairosnews readers:

• backstory
• blog
• bounce and bounce back (as in email, something we've all seen as of late with Sobig.f)
• CD-R and CD-RW
• DoS
• hacktivist
• Linux
• PDF
• postmodern
• ringtone
• roaming (as in mobile phones)
• virtualize
• warchalking
• XHTML
