I am way more worked up about this than I should be, but I have talked to people who believe HTML5 is slow, horrible and the worst thing since flash (probably no one actually said this but I think I’m funny) because of exactly this.
Because the employee’s of Facebook wrote an app with HTML5 for Android (iOS as well until the newer one came out which doesn’t use HTML5 technologies), and it is incredibly slow Mark Zuckerberg has decided to tell everyone that they made a mistake by betting on HTML5 too much.
Mark Zuckerberg, don’t call out a technology just because you (I doubt you ever touched the code) and your employee’s don’t know or understand it well enough to make something with it properly. If you had me (or any number of the proper HTML5 developers out there) write the app you would have seen the benefits and would never ask someone to write a native app again, open your mind to the web it is constantly changing and has left you far, far behind, it has left everyone still using PHP behind.
The reference below is an older article but the issue keeps popping up all over the place. I do not think I am the best HTML5 developer, far from it in fact, but it is clear you wrote this app in the quickest way possible instead of writing it properly, and that is why it is the slowest app I have ever seen, not because you used HTML5 technolgies.

-end geek rant- if you made it here, congratulations you made it through a poorly written blog post that started out as a Facebook status.
