The Internet abounds with all sorts of information on ipd, but unless you can be reasonably sure of its source and accuracy, be wary. For example, information about ipd posted in Internet newsgroups can be flawed. Even if the ipd document contains great technical detail, there is often no hard evidence to back up the claims. Don't make the mistake of accepting gossip as truth, which may prove to be professionally and financially embarrassing.
While embarrassment is rarely fatal, more serious consequences can result from following ipd advice posted in newsgroups or on websites. While someone may be well-meaning in offering the information, can you trust it? Is this person a ipd consumer who has actually purchased and used the products or are they just an opinionated individual? Or are they a competitor?
