If only. That sentence means that any videos with ads will display with the usual flash player, even if you opt in to the beta.
You see no benefits to using XHTML. I agree that many of its outlandish promises failed to materialize.
I see no drawbacks to using XHTML. I hope you agree that it is and will always be valid HTML5, which is The Future(tm).
Let us be as one mind and one people.
2) There's no XHTML2. The future is HTML5.
...which supports XHTML syntax and the application/XHTML+XML mimetype. XHTML syntax is still quite alive and well, and usable by anyone who feels like using it, like myself (I find the rigor makes things easier to read and write). Perhaps you don't like its strictures, but luckily there's room for both of our syntactical preferences in the W3C tent.
The value of your time is whatever someone is paying you for it. If nobody is paying you for it, then that time is worth $0.
I think the (monetary) value of your time is whatever you are or could be getting paid for it. In the example of the contractor you gave, if the contractor could have done billable work for another project in the extra three hours (though perhaps that's unlikely), then regardless of what you did or didn't pay, the hours were worth whatever he could have got for them. He sacrificed their monetary value in order to gain what he thought was a superior value in client goodwill (avoiding leaving mistakes in, appearing forthright and not greedy, etc).
Other commenters have noted that the auteur is a well-known publicity director, so presumably time that he spent making this video could have been spent on other things, and thus has non-zero value.
Some software patents are really business method patents (how someone navigates this page, or which button they press). Some software patents *may be* technological patents and should be measured as such. Blanketing software patents by comparing them to business method patents is comparing apples and oranges.
Apples which sometimes "are really" oranges perhaps should be given a closer comparative examination.
The end of labor is to gain leisure.
