I. Instagram
One of the most popular aspects of social networking is the ability to share ones images with others, and Instagram offers this, as well as allowing for an array of edits prior to upload. Integrated with several other large sites, it would seem to have achieved a position of dominance over its rivals. Honourable mentions go to the Internet Movie Database, a comprehensive factfile of nearly every film and television show ever made, Imgur, a simpler version of Instagram, in principle, that allows for the quick and easy uploading and hosting of images for use on forums and such, and the iTunes store, one of the first, and still one of the most popular, ways for individuals to legally download music files to their computers.
J. Justeat
Once upon a time, the ordering of takeaways had to be done over the phone, or actually involved travelling to the premises. No longer. Now operating in 12 countries, Justeat allows users to discover eateries in their local area and place orders with them, hassle free, serving as yet another example of how the web has made life simpler. An honourable mention goes to Justgiving, a site that provides a number of services for charities, offering online fundraising methods for charitable individuals to source revenue and see it transferred to worthy causes.
