Wikipedia subpages pros and cons

This page is the place to list facts and unbiased arguments about subpages at wikipedia.

Pro subpages

• Can be used to divide an otherwise long article into sections
• Can be used to store small amounts of data that could be useful but would clutter the main page
• Can be used to create small sub-articles that would look pityful on the top level but make sense within the main topic
• Known and used in the wikipedia community, removing subpages might cause confusion

Contra subpages

• Arbitrary decisions on where to create subpages / No rules on where and when to create subpages
• Two hierarchy levels are not good, either only a top layer or unlimited levels
• Can be visually unpleasant
• The switch to the PHP wiki might be the last chance to eliminate subpages
