Piling on to #2, get rid of the fancy animations and fade ins. For a developer audience especially this is meaningless posturing that's impressing no one.
I'm a hard disagree here as a dev. The timing is too slow for me (i'd half or third the delay) and perhaps lower the transition duration a hair. But the effect itself was quite nice and gave me a strong sense of polish and quality.
I'm in-between you and the comment you replied to on whether or not to keep the animations or if they add value. I kinda don't care one way or the other.
However, I think the current implementation is a real problem. I'm using an old phone. I scroll down and there's nothing but white for a while until things start popping up. It's blank long enough for me to start wondering what's wrong. At that point, I'm not really thinking about the content.
