I truly enjoy the finer things in life. For example, if I'm going to eat a steak I don't want some fatty low grade piece of meat. I would much rather (in this case, spend the additional money) to get an AAA grade of meat. The taste is worth it.
The same is true with development; the Twitter Timeline is "nice", but I personally don't want a linear, scrollable representation of my Tweets! I want the AAA grade where in this case it just takes a little bit more time instead of money… As you can see above, my Tweets are sliding in and out every 7.5 seconds. Once it cycles through my latest 10, it restarts again.
