If you aren't on Twitter, you really should be. It's not just a place to connect with other like minds, it's also a place to learn.
In fact, when you tweet important screenwriting news, information, or thoughts, start using the hashtag #ScriptMag in those tweets so we can all help each other learn. You can always catch up on what you missed during the day by going to Tweetchat and searching the #ScriptMag hashtag.
After all, social media is social. Being a community is the whole point.
