#compgov. If you are new to Twitter a hashtag is a place where you can ask others questions and/or "store" information which anyone can see later. For example, one of the AP Comparative leaders is Andrew Conneen. As soon as I made the post below on Gapfinder, he tagged it to the #compgov hashtag and now even more people can see it. This blog, the Facebook page for AP Comparative and the hashtag are all ways for you to expand your collaborative learning team - especially if you are like me and are the only AP Comp teacher in the building.
