Last few weeks had been hectic. I gave a presentation to hundreds on Apps Developers at HQ followed by another presentation to again hundreds of developers in India and finally a presentation at Oracle Open World 2007 at Mascone Center, SFO. The first two presentations were about three hours long while the last one was just an hour. There were some clear differences in three audiences. The developers in US were mostly senior level and interested in "what" while the developers in India were younger and more interested in technical details like "how to". The audience at OOW was much more senior level and was interested in a higher level overview and the direction of technology.
