Display links to your most 'interesting' posts, where interestingness is determined automatically by a Bayesian learning algorithm.
The theory behind the plugin's approach is provided in this document.
Options: Reset does the obvious and resets the statistics. Title changes the title in your sidebar. Number says how many to display. Show scores is the interesting one. It puts a an expectation value for the current interest score next to each item. The last (extra line) is the expectation value for the scenario parameter (that is, the fraction of people who are probably looking at the sidebar). I just added a fun feature: plot. When you click plot it shows you a graph of the probability distribution for what values the parameters can take. Note that it is unnormalized. At the moment there is no option in the widget pane, but there is a global variable in the php file 'processdelayinsec' which says how often to update statistics.
