#katebreak @ ad:tech sydney
A while back Kate Kendall wrote a blog post that noted a number of women named 'Kate' or 'Katie' who are involved in Australian women in online marketing movement (WOMM).

Coincidentally a bunch of women named Kate/Katie were attending ad:tech Sydney and were all tweeting as one does at conferences nowadays.
The idea that came up was for all the Kates to get together during a coffee break - it was quickly termed #katebreak. It was closely followed by requests by non-Kates to join us for coffee. Thus a meme was born.
We enjoyed a nice cup of coffee & cupcakes, it was pleasant to catch up with folks in real life (and it was easy to remember everyone's name ;)
