Just want to say that this is an
amazing product/service! It's really easy to use, time-efficient (Clocked in over 2 BTC with just over an hour and a half of work), and fun seeing your balance update in real-time. Great work, Warge, this project has some great promise.
The only roadblock (aside from underexposure, easily fixed) I see for this service is the shortage of work, such as the recent 18hr+ shortage (which I understand isn't your fault, Warge, but simply crowdflower doesn't provide jobs on a regular basis), which would hopefully improve as you get to be a longer customer with crowdflower and get more hits on your website.
Just as you use a CrowdFlower API to pull jobs and display them, I see at least a niche in the market for your own API. So far, your product seems pretty unique, no other mTurk-type work with BitCoin payout that I know (although I have heard of one proposed on another forum), meaning you might be able to capitalize on your own API, for people to embed in websites for donations, etc. (Such as embedded in a website for a gaming server that a player can log onto and drop a few minutes mining 0.1 bit coins as a server donation instead of spending real money) although I have no idea how possible this is being that you are already pulling from a proprietary API yourself. Just an idea.
As well, I noticed your website doesn't have too good of SEO (a search for CoinWorker on google has irrelevant results before your actual website, and BitCoin-related searches don't pull up your website.) Getting some better SEO may prove very beneficial, helping this awesome project go main-stream.
While this doesn't really currently work for a steady income, it is great to pick up some spending cash (especially when coupled with services to buy steam games with BitCoins), and might be marketed in such a way to entice people who would like to, for example, beef up their gaming library (if you are going to consider buying and placing advertisements) or buy some music online.
As well, it's awesome your keeping up with your growing community on Twitter, helps a lot to be able to ask/communicate directly with a developer.
A quick bug with your system (only a problem for people who don't quite get it) your system doesn't check on submission of a BitCoin address whether it is malformed or not (might want to at least check to make sure it is 34 characters) as a user can unwittingly enter a real address, name, or something else without receiving an error about their submitted "address".
The UI feels polished and works nicely, anyone should be able to figure out what to do quite quickly, very good for a website aimed at more of a general audience.
I agree with Vitality:
Are you familiar with Swagbucks?
They have a tasks section that comes from crowd flower and there are 15+ different tasks currently available.
CoinWorker would be a lot more competitive if it could offer those tasks.
Swagbucks (and many other sites, for that matter) offer a lot more tasks and options, again I don't know how crowd flower distribution works, perhaps it's based on how many tasks have been completed through you before? Anyhow, if you have any control over the tasks that you have on your website, of course the more the better, and all with good time I'm sure they'll arrive
.
At any rate, awesome service, awesome site, and very few bugs of any sort.
Keep up the good work! Really like this site, but you definitely need a larger variety of tasks which I know crowdflower currently offers.

Also wanted to say, to deal with the inherent problem with startups of underexposure, might want to put this on the bitcoin wiki (under something like earning or mining) just as simply a helpful inclusion to the growing list of other services (most very inefficient for earning).
