Not really.

Type in "quasar" on Baut and you get links to hundreds of different threads, most of which won't answer whatever question you had about quasars (such as "what is a quasar"), and most of which are filled with various offshoots of the OP. In fact, it would take someone hours to read through all the threads.

Type in "quasar" on Wikipedia and you get a well-formatted article, complete with it's own table of contents to the various sections, links to further readings, "see also's", references, and links to external websites about quasars (in case the Wiki aritcle didn't answer the question). And it doesn't take hours to read the article. It takes just a few minutes.

To top it off, the Wiki article on quasars did answer my question: Quasars are believed to be the output from accretion disks falling into supermassive black holes at the centers of distant galaxies.
