I was thinking of adding Cognitive but as Garr stated that they were tests I did not want to post information that may be misunderstood.
Looking at the page linked it does not list any things that could generate bitcoins as being owned or rented by Cognitive. I will just wait until they release actual dividends from the mining rigs just like I am waiting for BTCSYN and RSM to also do, unless Cognitive sends out another dividend and does not list them as tests again. I think Garr said in a few weeks the mining rigs will be up. I am a shareholder in Cognitive so I will know when that happens.
Maybe you're right. the 1g/s mining rig loaned to the Cognitive is some kind of IPO seducing, which should not be treated as a regular operation. And the young kids seems don't pay much serious attention to this 1g/s mining rig, and paid dividend from this loan rig in a random and emotional ("test") way, though the intention is good. Just like BTCSYN, the 6g/s mining power is rent to the company at the cost of half the company's shares, but they set up a transparent site to show the statistics of the mining rig.
