About 14 people attended my Introduction to Scala "talk". As I had no idea of the skill levels of the audience, I kept the presentation fairly generic.
I was very happy about the feedback I received shortly after the presentation. For the next meetup, I am thinking of doing something a lot more practical, some simple coding following the "Koans" approach.
ScalaKoans seems like a good start, I might use it, or make my own version with a more local flavour.
Many thanks to JoziHub for hosting the events: they are super nice people, the facilities are great.
I haven't yet scheduled the next meetup, but I am trying to run them on a regular basis (i.e. 2nd monday of each month).
