Don't think there was already such a thread so I thought I might kick it off.
Apart from 3 million cat pictures, fail compilations, hollywood gossip, sport and .. (and other entertainment) there actually are some great sites that can be invaluable sources of information and knowledge.
For my money I would kick off with
1) Whirlpool.net. This was started up by an 18 year some years ago in protest at Telstras ham fisted internet policies. For my time it is one of the best sites for analysis of internet options. However it also has a huge online community that offers wide ranging ideas on almost any topic. It's certainly one place I go when i want to suss out a potential scam, product or service.
2) On line university courses. I'm currently thoroughly enjoying Professor Jeffrey Sachs course on The Age of Sustainable Development. Very comprehensive and pretty accessible.. Certainly opened my mind to some new ideas.Of course there are plenty of other courses also available both at Columbia University and other places.
Has anyone else got websites that they believe offer quality information/ideas ?
