With a billion tweets per week, there’s no question that Twitter has become a popular social medium. But while not every person is a Twitter user, it is important that everyone at least know what Twitter is.

I’m starting to see malware-bearing spam that preys on the popularity of Twitter, though anyone even remotely familiar with Twitter would never be fooled because it displays a complete ignorance about how the twittersphere operates. The latest is a message from Twitter Support indicating that there are a number of “unreaded messages” awaiting review.

There are other dead giveaways to this initial spam vector, but social engineering techniques will undoubtedly improve over time. The fundamental issue is that even a non-user should be taught that Twitter is not a messaging system in the traditional email sense, so as to not get fooled by the spam into clicking to see these “unreaded” messages.

Make sure your non-Twitter friends and family “faworites” know the basics.
