Today there is significant peer pressure within this global generation of many social individuals using the internet and web based media tools. Unfortunately many of you internet users have not considered the importance of protecting your personal identifiers (personal traits, habits, and information) and have made yourselves very open (vulnerable) to the international front in using the many creative tools, i.e., blog spots, MySpace, Facebook, Twitter, and other media tools. Readers be aware, the more you communicate about yourself, the more information your future employers can find out, your insurance companies can mine on you, and especially
malicious social engineers can collect on how to appeal to you, capture your attention to them, etc. Today there are many internet lurkers with an agenda to take advantage of your 'trust' (using what ever information they can gather to appeal to your trust). Also other's make money off of collecting information on you for providers, such as investigations services for insurance companies, corporate human resources, and more.

Advice today: always be alert to how much information you are giving out on your personal identifiers (driver license numbers, social security numbers, passwords, address, phone numbers, banks information, credit reports, and especially genome sequences).
Social engineers look for more identifiers such as live style habits, your personal desires, your reactions to things, etc. on these open public channels. You may want to review what information you have already given out, to know what some have collected on you already and can be using. Think before you post. There are thousands of social engineers out there gathering the data and profiling (especially if you work in any area that they may profit from).
