Sunday we had our 4th and largest Barcamp in Saigon. About 570 showed up to the premier free and open tech event in Vietnam. Here are 5 of the things I took away from it.

1. The most people sign up in the last few days before the event.

Traditionally, we would get a 50% show rate of the registrations but this time we had 999 people sign up and 570 show up. Without any setup for cross-checking registrations we don't know how many showed up without pre-registering. Because so many signed up after we settled financial calculations, it wasn't possible to accommodate the unexpected people with free food.

2. Barcamp is a recruiting event. Sponsors came with recruitment in mind. Non-sponsors can also try to muscle their way in. Giving a presentation is a great way to advertise your company and the people who ask attentive questions might be good hiring candidates. But giving a presentation as an individual is also a great way to advertise your hireability to companies.

3. Morning rush - everyone should have an equal chance in getting their presentation on the schedule as long as they show up to the opening. But it's kind of chaotic. When the dust settles, most sessions are in the morning while the afternoon schedule is sparser. A lot of people end up leaving before the closing ceremony and t-shirt giveaway, not that there's a problem giving out all shirts. Other Barcamps do it differently. Some use a voting system and I've thought about some implementations for next time.

4. Serial event organizing needs (infra)structure to make organizing less stressful over time. Without huge Google or Microsoft campuses in town, we're lucky we do have the large (although far) and impressive campus of RMIT to depend on. If we want to go Yangon-scale, we may need a totally different location.

As a tech-heavy event with talks on web scalability and high throughput, it's no good when the official web server falls over under load (I blame Windows). Good internet connectivity at the end is also a must.

Other skills the organizing team needs: Fund-raising, logistics, graphic design, legal, and the ability to get the word out.

5. Outsiders are awesome. I'm really grateful for the guys who brought Barcamp organizing experience from Cambodia, China, Southeast Asia, Germany, etc. to Saigon to share with us. Barcamps are often bootstrapped by foreigners. Outsiders also expose us to new ideas in technology. But I was happy to see at least some local ideas find an audience in the foreign attendees.

Barcamp isn't just about the sessions. It's as much about people coming together and sharing ideas outside of the sessions. The organizers' task isn't to control who speaks, unlike traditional conferences. Our job is to provide a platform for everyone to share knowledge with anyone who is interested. The trend, I hope, is for more people to realize that they do have knowledge that's interesting and worth sharing and to give them the opportunity to speak in front of an audience and further develop their ideas when putting together their presentations, and also get feedback from strangers that they otherwise would have never met.
