Questions:

1.Do you think that there may be a business opportunity for such a website?
2.Would you be willing to participate in one way or the other?
3.Would you be interested to publish your game on that web site?

1. Always opportunities, its whats done with them that counts.
2. Not really...would make my own site and link to established market nodes.
3. Depends on hit rate, popularity, exposure etc....
