Definitely worth reading. Note that it's a series of 3 articles, the last coming tomorrow [June 10].EDIT: Pointers Special: Security Best Practices – Part 3
The "problem" is that almost everyone who frequents these forums are at least moderately savvy with respect to security. Those who most need tutoring are oblivious to the need until they get hacked/scammed/defrauded.
And even though the articles are directed at a Mac user audience, the general principles apply equally to PC users.
In all these cases it might not be a bad idea for forum users to pass on the URLs of the 3 articles to those who can best profit from same.
