Talking GeoBabel In Three Cities (And Then Retiring It)
You're invited to speak at a conference. Great. The organisers want a talk title and abstract and they want it pretty much immediately. Not so great; mind goes blank; what shall I talk about; help! With this in mind, my first thought is normally "can I adapt, cannibalise or repurpose one of my other talks?". This sometimes works. If there's a theme which you haven't fully worked through it can serve you well.
But a conference audience is an odd beast; a percentage of which will be "the usual suspects". They've seen you talk before, maybe a few times. The usual suspects also tend to hang out on the conference Twitter back channel. Woe betide if you recycle a talk or even some slides too many times; comments such as "I'm sure I've seen that slide before" start to crop up. Far better to come up with new and fresh material each time.
