Mobile Web Reserach and Twitter Info

I did some research about how much use each mobile platform gets for browsing the web.

I looked at two different reports, which both basically said the same thing.

In North America, when people use the mobile web they are pretty much on iPhone, Android or Blackberry.

iPhone: 50%-60%
Android: 10%-30%
Blackberry: 5%-10%
The rest: < 5% each

Just wanted to think about twitter for a minute. Twitter gets huge percentage of its hits from mobile and processing almost a billion SMS messages a month.

They've also said that their blackberry app gets 8% of their new sign-ups:

.closest does not mean closest!

I found out recently that jQuery's closest() function doesn't find the nearest instance of the selector, but instead find the nearest parent that matches the selector. This is a really important difference and I just thought I would highlight it!

Functionally Equivalent

  // not sure if we need $(this).dequeue(), but it works alright
  $(this).before( $(""+msg+"").delay(1000).fadeOut("slow").queue(function() { $(this).remove(); $(this).dequeue(); })  );
  
  // use the built-in callback
  $(this).before( $(""+msg+"").delay(1000).fadeOut("slow", function() { $(this).remove()}) );
