'Meow' is Category based - it picks an article with the following process:

1. Pick a non-hidden category of the current page at random

2. Pick an article in that category at random

3. Go to that picked article

'Linky' is simpler:

1. Pick a random outgoing wikilink of the current page

2. Go to that picked wikilink

'Closer' is slighlty more complex, and works only when you have used 'Linky' at least once:

1. Make an intersection of all links that were present both in *this* article and the previous article

2. Pick a link out of the intersection at random

3. Go to that link.

Which one do you think gives you the best 'related to the current article, but slightly random' results?
