The Who, the What, and the Why of Intervention:


I am webcomic creator, artist, and blogger Oni Hartstein. I and web developer James Harknell founded Intervention together in 2010.

Unlike many other events we both serve as Co-Con Chair every year and oversee every aspect of Intervention. If you’ve ever attended Intervention you already know that we are obsessed with providing a great attendee experience.

“It’s the best con I know of that’s geared toward independent creators and helping people get their work out there, among other things (there are plenty of nerd culture cons, but this one is the most con-goer friendly if that makes sense) And there’s no air of superiority/holier-than-thou-ness from the staff of the con.”

- Phil Gorski

What and Why:

Intervention is different from every other event you have ever been to. Our name is the combination of the words “Internet” and “Convention” but the significance is deeper than that. The entire idea of this event is to Intervene and Inspire everyone to live a more creative, geeky, and fun life within the welcoming scope of a traditional geek convention.

James and I both worked our way up from a disadvantaged situation. Art and (most importantly) the internet was how we were able to make our own opportunities and rise above all of the awful. Whether creativity is your serious business or just something that makes your life better – the result is the same. Good things happen when you make things.

When I would exhibit at cons I would meet so many people who would tell me that they felt their life was hopeless and that they could never do what we were doing. The thing is – we are not special. The only thing we did was never give up. We spent so much time sharing our knowledge about the opportunities the internet offers that we knew there was a need for an event to encompass this new way of making things.

“Welcome to our creative and geeky DIY world. Life doesn’t have to be boring. Maybe you just need an Intervention!”

YEAH, I SAID IT! I just quoted myself while typing in the first person.

But in all seriousness I’ll let our track record speak for itself. Scroll back up and click the buttons on the right nav bar to get more information on what we do.

The best part? What we do changes and gets bigger and better every year. If you have something to contribute, you could be presenting. We are about the art – never about elitism. Elitism is for people who aren’t good at what they do.

This is how the next generation of Geeks get their party on.

Join us this year.

    is there a minimum age for entry to intervention?

    • Harknell says:

      Hi Ben,
      Children under the age of 12 need to be with their parents at all times, so that would be considered the minimum age limit. 13 and above (with parental permission to be at the event) can do the events by themselves if they wish. We are a family friendly event (with a small number of 18+ events that will be clearly marked and restricted)

  3. [...] you are unfamiliar with our brand of geekery, look no further than our About Page, and the Archive on the top navigation bar for examples of what we did and will continue to build [...]

    Noob question
    how is thid convention different from other
    conventions and is there gonna be people cosplaying
    sori for the noob questions

    • onezumi says:

      Many people will be cosplaying, but we don’t have formal events for it yet. We are focused on educating people about how to put their stuff (comics, art, podcasts, videos, blogs) up online and monetize it.

      The other half of the con is a festival of indie geek artists, board and video gaming, fan geekery, and crazy performances like Harry Potter belly dance and Cosplay Burlesque. So if you are a creator looking for help or just a fan who wants a most excellent party, there is plenty to see and do.

  6. Lee says:

    Hi, there,

    I love the idea of your convention! I only wish that I can go, but I’m too far away and my time is sadly very limited. I see that you have some video up… will you post more video of the panels and events? Is there anything like what you do in the NYC/NY state area? Please let me know.



    • onezumi says:

      We intend to post more video – unfortunately last year a lot of the video did not come out. Hopefully it will be better this year.

      I don’t know of anything like us in NYC. We actually live in NYC/NJ but drive to MD to do this event because the costs are so high up there. If you decide to come one year, it’s really easy to get to us via Amtrak and BOLT Bus from NYC. :)

  7. Isabella says:

    do people cosplay, and if so what kinda of cosplays are there, can you wear any cosplay like from naruto to sailormoon?

    • harknell says:

      Hi Isabella,
      Yes, we do have Cosplayers at the event, and any of those outfits are fine. We have a few panels on cosplay design, so you might be interested in those. We may even have a small cosplay hallway contest happening this year, so look for that on Saturday.
