Twitter not updating tweets
What's really important is how the new timeline works in practice.
The algorithm that will re-order your timeline is based on the one that ranks tweets for the "while you were away" feature that Twitter introduced a year ago.
We wrote this plugin so everyone could have it at a click of a button.
There are a few Twitter plugins out their, but we couldn’t find one simple enough, or that worked (to be honest) and so the Simple Twitter Tweets plugin was born.
The best way to think of the new timeline is as an expanded version of this feature.
