Blogging is still a viable online business idea, and one with as much potential as ever. Just make sure that you start a blog on something that people actually want to read about. If that happens to be something you're passionate about that's great. But you need to understand that it's way easier to monetize a blog about organic dog food than it is to make money from a blog about obscure literary fiction.
How to Get It: Begin with sites like UserTesting.com, YouEye.com and Userlytics.com. Register with multiple companies for opportunities to test as many websites as possible. Once you're in the system, you'll be emailed when testers are needed, and if you're one of the first to respond, expect to spend 15 to 20 minutes completing the test. Many sites require a microphone and/or webcam, which are built into most laptops—but if you need to buy one, they aren't expensive. The tester sites typically pay within a week or two via PayPal.
