I suppose that if one were to dig in and read all the ebooks and follow the advice of the gurus, you could develop a talent for Tweeting that could produce some useful activity. For now, I can't bring myself to put that much effort into it.
Instead I have a Twitter account that I use mostly for Traffic Swirl tasks.
In order to get the Daily Bonuses, everyone needs to complete a task every day and one of the tasks I offer a lot is a Twitter Retweet.
To prepare, I Tweet a message suited to these folks and pin it to the top of my Twitter feed. Then I set up a task to retweet that particular one, but rather than link directly to it, I send them to my feed and ask them to look for it (it's right on the top) and most of them will at least glance at the content.
In my opinion, this gives me targeted qualified exposure (even if it is one person at a time) for nothing more than the 30 seconds it takes to set this all up.
Some of them appreciate doing a task where they don't need to join anything new or subscribe (which they can only do once) to something, they can come back and retweet every time they need to complete a simple task to get their bonus for that day. I don't offer enough credit to get those who do it over and over when there are much easier ways to get them.
Nor only that, but as I teach more people to do this, it makes it simpler for me to get my own daily bonuses.
