You can type in any keyword, and get the latest tweets containing these keywords across the entire twitter network!
For example if you're in the mmo niche, when you type in "i want to make money online", you'll be able to zoom in on the exact people who are hungry for your product!
This is powerful stuff guys!
Hmm.... IMO and experience, twitter is far from the best use of your time if you want to make money.
It's far more useful to setup simple websites, monetize them and, importantly, build an email subscriber list. A simple site monetized can earn you a few hundred a month (sometimes much more) so you just repeat it till you reach your income goal.
For longevity - and the big money - you use your site as one of the methods to build a responsive email list that you can promote products to over and over again.
