IMDb.com
Are you a cinephile? I hope so!
And if it so, then IMDb.com (the largest Internet movie database) could be rather interesting for you.
IMDb is a really great project. As a movie fan, I'm loving it very much. I'm not fond of a kind of bestsellers movies, and in this case IMDb helps me a lot by providing an ability to find not so well-known movies but truly more interesting and qualitative ones (as for me, of course).
But wait a minute, how can it help us with learning English?
Wikipedia is a really great project, which can help us a lot with learning English. Practically all wiki articles are good quality with no grammar or other mistakes - it's worth to admit that it's a big value for the project with user generated content, on other social sites such as forums, blogs, social networks and so on, almost always nobody watching users' language and correct mistakes. With wikipedia you can be sure - all articles have no mistakes. And of course wiki in most cases contains well structured and useful information, so it's easy to find what you really want. And besides learning English, wiki helps you to improve your education as well.
I guess practically everyone knows site
