Johnson & Johnson (JNJ) announced Monday that it is recalling 1-Day Acuvue contact lenses sold mainly in Japan and other countries in Asia and Europe. None of the recalled contact lenses were sold in the U.S. or in Canada.

The company said that it received a "limited number" of complaints from Japanese customers of unusual stinging or pain when inserting the Acuvue lenses. The recall started on August 18 and was not immediately announced in the U.S.

Given my position as a long-time denizen of the dot-com world, with dozens of contacts in new media and venture capital and all of the numbered Webs (1.0, 2.0 and maybe even 3.0), I'm quite frequently invited to things. Some are valuable networking tools, like LinkedIn; others are fun and a bit useful for keeping track of my virtual colleagues, like Twitter. Still others, like AIM, are vital for day-to-day working life.

And then there are the sites where my so-called "friends" hang out. It seems quite ironic that many of the former colleagues and distant contacts who invite me to "keep up with what he and your other friends are doing" were never what I would categorize as "friends." Vexing rivals? Quixotic bosses? Difficult customers? Unhappy underlings? Probably more like it. While I understand that social networking sites like Facebook.com and StumbleUpon and, to a lesser extent, MySpace and del.icio.us and the rest of them, are the rage right now -- and are used by many legitimate corporate types for actual work purposes -- well, I'm highly uncomfortable with the rampant use of the word "friend."

Let's face it: even if I'm pleased because Brian in Legal delivered that contract to me quickly, he's not actually my "buddy"; nor is the receptionist you just hired ready to be asked to join your "circle of friends." Plenty of people with whom I could happily carry on pre-conference-call banter, while I'm sure they're quite lovely, just aren't friends. Flickr gives us a break and lets us designate lots of "contacts," while Twitter has recently changed its nomenclature to count those you are following, and those that follow you. This makes sense to me! This is not presumptuous or uncomfortable.

Just because my name is in your contact list, Mr. and Ms. New Media Executive, it does not mean that you are my friend.
