Well, this is truly a good work, but there’s a few things that still are missing. For example, Facebook does not wait for the user to reach the actual bottom, else he would have to wait for the items to load and have nothing to see for a while (depending on your server speed). Also with this system it is preferable to load a lot more activity items than the default number (study what Facebook exactly does and you’ll see what I mean).
I hope this can be a good point of reference for improving. The code I gave in this thread is already doing that so you can take a look. Another thing, you should use throttling for avoiding several simultaneous requests that may load your server’s speed.
Keep on the good job!
