First, Erin Ochoa tweeted that she had posted her reflection on EdCamp Edmonton. We did a joint session together on using Twitter that day, although we were nearly 1,500 miles apart. (I wrote my reflection on that session at EdCamp Grand Rapids here.) It was good to be reminded of how Twitter supports professional collaboration.
Second, John Spencer started a Twitter meme with #pencilchat. He explained how it started here. Seventeen hours later and it is still going strong. Whatever the reason behind #pencilchat, it provided a lot of teachers with a laugh. And I for one could use the comedic relief.
PS The link in the tweet above pointed out another positive aspect of Twitter - connections. You can find out why here. I don't want to ruin the "rest of the story" surprise.
