What’s so great about !!Con?

Here’s what some of our past speakers and attendees said about us:

“@bangbangcon managed to pack more useful info into one day than most other conferences do in 3. And it was 10x more fun.” – @johnwittrock

“Virtual @bangbangcon’s reminding me how much fun it is to hear people talk about what they’re passionate about” – @trudake

“It’s refreshing to learn 30+ new things about programming in a single weekend at @bangbangcon, even though I’ve been programming for so long” – @pixelyunicorn

“@bangbangcon was awesome! Learned a lot, met very friendly people, and left inspired.” – @bxmani

“It’s only halfway over, but @bangbangcon is setting the bar for virtual events for me. […]” – @lazerwalker

We hope !!Con 2021 will be at least as good!
