Local chapter presentation topics.

Im curious about presenting one of these topics below at a local chapter casual conference/meetup. Could you savage bastards warn me off. I'd be targeting a local ISSA or local casual monthly chapter. I'm not looking for business development, but looking to support the field/trade. I'd be speaking from experience on what I think could help the less mature companies. I'd still be worried what the grey beards will think. ​ Enterprise COTS installed
