IMO there is no worse source for information than ehow.
Do yourself a favor. Pick a couple of subjects that you know a lot about. Look up those subjects on ehow. Decide for yourself if the information on ehow is worth the disk space it's stored on.
I can't tell you how many times I've read stuff on ehow that was at best so general as to be not worth reading or at worst completely wrong, such as the R&R instructions for a car part where ehow had the model/year incorrect. Their instructions weren't even close.
