pin is undefined, with 35 questions and many meanings:

• Damaged pins on chips, connectors, etc.
• Personal Identification Number
• Connector configurations
• Anchoring an application, folder, etc.
• Deskpins

It's a candidate for cleanup.

There appears to be some commonality with Poke a hole in "Pinning", which, like the weather, was talked about but not acted on. Maybe both of these could get the official status-planned tag.
