Here come the niche Wiki launches. Following on from JobberWiki, the career information resource site that anyone can edit, comes Tiptheplanet.com (quoting):
Tiptheplanet is a project to create a green wiki website that encourages discussion and the generation of tips that benefit you and the planet – From tips for individuals about staying happy and healthy to tips for multi-national companies to limit their carbon footprints, with accompanying explanations.
The site is coming out of the UK and has a nicely random feel to it, as in: “Switch to green energy; Find out about distributive power”. The site has been launched by Tom Savage, who also run Blueventures.org, a not-for-profit organisation which facilitates projects in global marine conservation and research.
