Introspection is the key

Many prophets and apostles have told us that technology is not inherently good or evil but how we use it can be. There are many ways what we do can be evil. The most obvious is to do something inappropriate, such as viewing pornography. When things like this are happening, it is usually pretty obvious that what we are doing is wrong. A slightly more subtle problem is using it too much. Most commonly this is playing video games or using social networking sites excessively.  To know if we are using technology we need to be in touch with the spirit. Make sure you can still feel its influence during the activity.  Also ask yourself if you would be willing to act on a spiritual prompting if one came while you were playing. There are many other problems that can come from the misuse of technology, we can only know that we are misusing it through personal introspection.
