depends, much of the info is put on by sincere and knowledgeable Muslims, but i did notice on some threads that there are vested interests with high privileges - especially on the political threads, you have to look at the info and then research for yourself, that is the nature of information, even in books you will find that authors have added made up tales. one has to sift through and when uncertain, use search words to find Islamic sources.
it is a good source of reference to start from though as there are a lot of Muslims who take the time to add info which is difficult to find elsewhere.
