Unwanted Stuff...

Enter Freecycle

...and Freegle

Freecycle Yahoo group

The rules

No LivestockNo TradingThey’ll never take our “free”dom! Aww...kitties....

Yahoo groups - the problem

•Users complain of toooo many emails•No API or RSS feeds •Subscription and first email are moderated•No link between images and messages•No standard for subject lines

The Problem for automation: Subject Lines

What the subject lines should be:

Offered: Brown computer desk (BS5)Taken: Brown computer deskPromised: Brown computer desk

Examples of the reality:

Offered: single mattress: BrislingtonOFFER: Huge tub of freshly harvested white grapes (Dursley)Offer: half-height fridge freezer BS8Promised: Single Mattress: Brislingtonoffered two wooden chairsOffer: Modern Tropical Fish TankTaken: White tropical Fish tank
