So far I've made about 40 or so euros, using only UHRS hitapps. Keep in mind that the first 2 weeks were great, and I had some
nice HitApps to work on, but as a non-US resident, I have quickly discovered that usually there isn't much to do on Clickworker.
I still occasionally check for HitApps, but its been a while since I last saw one worth doing. Perhaps a couple of weeks ago.
In my experience if you are American, Clickworker can do wonders to your income. Even if you are not, though, it's still worth registering and checking every once in a while.
There just isn't enough work there available to get done for it to be worth it. You're way better off joining Microworkers and/or Crowdsource. I'm on both and I'm happy with both. I like Microworkers much more because there's much more work to do there, but I like that I can make a few dollars a day with Crowdsource too.
What kind of work do you perform on microworkers and crowdsource?
