Yes, this is a cool idea. Use the share buttons on your channel to always announce your stream before going into action ;)
You can also submit your channel to Reddit through your dashboard.
Your stream can be automatically twitted if you connect your Twitter account to your Liveedu.tv account. In your Dashboard, go to the Notifications tab and click in CONNECT TWITTER ACCOUNT.
Now, you can also automatically announce your stream on LinkedIn. All you need to do is connect your LinkedIn account to your Liveedu.tv account in your dashboard.
