Be careful out there

There's some pretty reasonable advice at eWeek in Ten Not-So-Simple Rules for Using the Internet. I am increasingly concerned that the bad guys are winning and that the obvious potential for good that the internet has is being nullified by their activities. I've seen several wikis and even blogs where editing has been turned off because of abusive, obscene or spamming posts. I've seen blog comments being abused to manipulate search engine results. I've had to clean up PCs for several less IT-savvy victims when the burden of malware became so great that the PC barely functioned. The very openness and accessibility that makes the web so great is also its Achilles Heel, and as is usually the case the power of a bad guy to negatively affect others is greater than the inverse case.
