500px Terms of Service
As much as I think Terms of Service documents are broken, I don't like these supposed simplifications, because invariably they simplify too much.For example, in the real ToS, there's this clause:    The license granted to 500px includes the right to use your Content fully
    or partially for promotional reasons and to distribute and redistribute your 
    Content to other parties, web-sites, applications, and other entities (...)

This is, in my opinion, an important clause that does not appear in the simplified version of the text.
