I like wikipedia. I look at a lot of pages about contemporary culture and philosophy. A lot of these pages are tagged as inaccurate, vague, and/or without citation (such as Nietzsche's ubermensch). However I still find pages such as these helpful in my own reading of the primary source.
I suggest pages like these recommend users to check the primary source for a better informed reading. If they are reading a page in English trying to describe the primary source, then reading the primary source itself shouldn't be impossible.
