It seems like you're being sarcastic, since the hackathon took place in the past and, therefore, signing up is no longer a possibility. Despite the exhaustive observations you surely made while not attending the event, I find your insinuation that only teams of back end developers have the qualifications required to organize hackathons to be facile and, frankly, untenable.
I think that the founders came from heterogenous backgrounds is, in fact, a positive thing. Part of the point of the hackathon was to create an environment that values different perspectives. The fact that the organizers have experienced the tech scene from avenues other than coding gives them different perspectives, which, all other things being equal, is probably a good thing.
Perhaps all else is not equal, but I'm not convinced. I volunteered at the hackathon. The hacks were quite good and--possibly more importantly--the atmosphere was phenomenal. People worked and played well together, and a number of individuals made comments to me along the lines of the following:
- I feel really comfortable working at this hackathon.
- This hackathon is really well-organized.
- I appreciate that this hackathon doesn't require me to do unreasonable things like sleep in this office, or not sleep at all, or expect me to do tequila shots like other hackathons.
I'm sure a team of 4 back-end devs or 4 startup CEOs could have put together a similarly great hackathon. But is that sort of team composition a necessary condition for the event to have been a success? No.
Reladtedly, how funny/sad/appropriate is it that in a discussion involving the exclusion of females from the tech community, someone would protest that teams composed of non-developers should be excluded from organizing hackathons?
