Twitter Meetups
A twitter meetup is when a group of followers discuss a topic using hashtags at a predetermined time. Sometimes this is spontaneous, such as a political debate. Other times these are planned weekly or monthly events.
Ever seen #FF? That's an example of this on too broad of a scale. A great example of what I suggest you do is #blotchat. They meet weekly for a few hours and network/discuss blogging.
Create something similar for your audience, it works really well for bringing in traffic. Then after it's over, create a list if the best commentors and their comments in a post. This way they will retweet the event since they were featured last time.
