what do those sites have to do with this forum ?
other than bitcoin in the title?
don't mean to be rude, just asking.
Bitcoinget is a pay to click site like many others that are often discussed on the forums, e.g. Bitvisitor. I used to use it a lot and still check in there sometimes. Basically it is like mechanical turk but for bitcoins.
Hiki - I don't know what the issue is with you and crowdflower, I've never tried to register but it does look like that more and more tasks require it. At least you can still do videos.
