OK, I'll take a stab at them. (Yes, I did read his Important Note, but why not?) Status:

1: No

2: No (I think). I don't know if Google App Engine is making money for them, and Github doesn't host apps, and Amazon Web Services doesn't (only) host open-source web apps.

3: Hopefully.

4: Doubtful, but one can dream =)

5: No.

6: HN? Is Steve Yegge here?

7: Yes. I think it's valid to put the iphone's success in 2009 (rather than earlier) due to the large number of apps and growing number of competitors in that year.

8: Well, considering he's working there, I think he's being paid instead =)

9: Probably.

10: Yes, although it's not a tautology. (You could have asymmetric heavy tails which would make most programmers below or above the mean.)
