twitter hashtags for science education

How many of you science ed folks use twitter? I've been trying to build my network of educators (science and other) on twitter and have found some really interesting folks, especially in the EdTech field. If you are familiar with twitter and hashtags, I propose we start tagging tweets related to science ed using the tag #scied. I know of one twitterer who does something similar in math ed. I've also started using the hashtags #AERA and #NARST for discussion of the respective conferences. Anyway, I'll give it a try and see if anyone else tags similarly.
