My husband once told me about a friend of his who was committed to picking up every coin he saw. At the end of a year, he was surprised to find how much money he actually made by simply bending over and picking up change. I have the same philosophy with some of my online endeavors.
I came upon BeRuby.com a few weeks ago. It is a portal site that leads you to the sites you visit often (twitter, gmail, google). Every time you log onto beruby.com and then click on your mail icon or google icon you make a penny or so. So now, rather than clicking on my gmail icon to read my email, I click on the beruby icon, then click on my gmail icon. It takes one extra step and I can earn a penny or two when I do it. In the few weeks I've been there I've made nearly $5.
They also offer percentages back if you use some of their links to purchase things online. So, for instance, you want to send flowers to your aunt you can go through beruby and get 5% of your purchase right back. Over time, this can add up!
You can also earn a dollar for every person you have sign up UNDER you up to $5. Then you make a percentage of everything they make. So, the bigger your network, the more potential you have to make money.
So, as far as I can tell it's definitely worth trying. There's nothing to download and I haven't gotten any spam from them.
Here's my referral link.. I'd love it if you signed up and used it!
