Maybe there could be a stock photo or video section in the Gig Guru site. Most phones have a decent camera and they could take some pretty decent footage. Also there could be a travel section. Local people, updating with locally known bars, restaurants, bus times, train times, local prices, hotels. People could subscribe to the travel site and thumbs up good info giving that uploader ETN. Much better information than a book as it could have daily updated news.
Stock Photos is a world on its own. I would highly second that though.
Just uploading pictures from your phone and start earning ETN sounds really nice
