the ancient metateros may have done the same. filomeno gabrielmateo has only enough land to feed his family and a few animals. there is not enough to grow surplus produce to trade for other goods. interpreter: there's definitely not enough to sell, but the harvest does provide enough for the chickens and even the donkeys. we go and get firewood and the donkey must be in good condition. also, we raise pigs. we may sell a pig, and we also bring in money from the sale of chickens. keach: between farming chores, filomeno and his uncle edmundo make manos and metates part-time. anything filomeno can do to cut production costs would be to his advantage, even to the point of making some of his own tools. production is just one aspect of specialization. another is distribution. filomeno must get his metates to market. the copan metateros faced a similar problem. for them, the solution was more difficult. an expert on ancient systems of transportation is ross hassig. mesoamerica had no wheels that were usable in any meaningful sense. they had no draft anim

gabriel: i can tell you, the things we have done, and the kinds of things you can write from us going forward. some of you may look at this as just fixing bugs. some of them have been more or less difficult. historically, we have done a pretty lackluster job of making it possible to even report abuse. the amount of hoops people had to go to through to say people were engaging in an abusive manner. it has to be the case that it is easy to report the abuse as it is to do the abusing. in our case, it was easy to engage and hard to report. that has been something we have gone out of our way to fix. the next step is, i think in balancing the ability for someone to express themselves but giving someone the ability to not have to be exposed to abusive behavior. the next step is -- for those of you less familiar, we have an asymmetrical follow draft, which means we can follow each other but it can also be the case that i follow you but you don't follow me. part of what our thinking is if you are sending tweets to me throughout the day saying you are a jerk, if we follow each other, i am saying i want to hear you tell
