Webinar = Commercial

Going through the Twitter data collection I see that webinar means commercial ... click to URL and you are greeted with cheesy graphics of earnest looking people in suits on the phone, looking at a computer, smiling around a conference table with words like "strategic / "newest" / "monitor progress" / "agenda" / "goal alignment". In contrast, teachers and other edtechers just say something like " Catch the live stream of blah, blah" or "So and So is presenting over at ..." Just a wee example of the culture and language embedded in the network.
