I've gone to the grocery store and pulled a bunch of sweet potatoes out of the same bin only to get to the cash and have some wrung through as sweet potatoes and others as yams based on the colour of the skin. It confused me. I imagine the cashier was confused as well.

No they aren't yams. Sweet potatoes come in a bunch of colours.

The article describes that nothing (or very rarely) in North America will you actually find a yam. Sweet potatoes just look like yams from Western Africa and slaves started calling them that and the name has stuck.

Maybe I am missing something... but I haven't actually seen what the goal of this is? What is the problem that it is addressing?

hubski is already dominated by a small group of contributors. Is it that you don't want anyone new to join and want to continue hanging out with the same people? My understanding of how the website is already set up is that the more people like something or someone the more influence that person has, which already reduces the chances of new users having a large impact on the site?

Well I guess that I will just have to learn Dutch then... or convince them to open a franchise in Canada.

BC has got Family Day too.. they just put it a week earlier.
