Well it's officially in the books and GeoConvention 2019 is done. Thanks to Dustin Menger and the GeoConvention committee for accommodating my 11th hour addition!
The reason I was in the 11th hour was that I was not sure I was going to have a 'ready for distribution' version of EESi LAS Viewer by the convention exhibitor deadlines. Client projects in the past few months took precedence over final touches and quickly the time was squeezed. Since I am the sole owner and operator of this endeavor, all activities are sequential in nature - marketing does not happen in parallel with development. Yes you can round-robin it but it's still one step at a time (just like hiking up a mountain).
As a developer I usually don't spend too much time thinking like a marketing professional so am quite naive about what goes into that job. This was my very first experience as an exhibitor at a convention and having to go through the process of pulling together an exhibit in such a short time frame certainly gives me much more appreciation for those who do it daily/weekly/monthly.
Although that helped me get through the setup and opening day, I'm certain the impact was on connecting with my potential audience - so thanks to those people who were able to see through my low-tech marketing, stop, say hi and ask about the viewer.
I enjoyed meeting you and hope this product helps you. Please reach out if you have questions, comments or suggestions. If you picked up a feature sheet, note the coupon code for a discount at checkout - if you missed picking up a feature sheet then send me an email at firstname.lastname@example.org.
If you are reading this and were not a convention attendee then also feel free to send me an email - but to get the coupon code you'll have to tell me what you are up to (i.e. how will the viewer help you), just like you would have done had you visited me at the booth ;-)
In summary, I would say my learning and recommendation would be to try to avoid low-tech marketing if at all possible, get help if you can (I now have business cards of companies that specialise in this ;-), but don't be afraid to exercise the low-tech marketing option as a last resort.
