Jane Wells nearly missed her flight to SXSW:
In this case the gravatar on my business card saved the day — and the SXSW WordPress Party, because if I’d had to drive home to get my ID, the chances of getting a new flight to Austin would have been pretty slim. So! The next time you’re having cards made, consider including your gravatar. It just might save you someday.
If you don’t have a Gravatar yet, you should seriously set one up already.
