Here's a couple of things I think should be discussed at unconference.
* TV advertising. Not really advertising of your products, rather advertising how easy it is to repair, and spread the word about repair and iFixit.
* iRobot improvement. It would be awesome if iRobot could also get rid the "I have this too" posts. Maybe also switch answers to comments.
* Giveaways. I recently learned about this [https://www.amazon.com/ga/giveaways?ref_=pe_2644850_248838590|Amazon giveaway]. The giveaways aren't hosted by Amazon but rather people put up these items probably because they like them. I'm thinking iFixit could do something similar.
