If you’re a Facebook user, you’ve probably come across the newest Internet sensation – What I Really Do.

Through a series of photos (usually six), people from various professions extoll the opinions of what their job entails. We’ve seen them for journalists, accountants and yes, even marketers.

It’s a cute idea – one that almost definitely will become the next big seller in posters right next to the famed demotivationals. (And if no one’s started this year, we’re putting out a patent pending on it.)

Naturally, companies are going to want to take advantage of the latest meme (hot ‘net trend), much like many did for the “sh** suchandsuch people say” trend that was all the rage for 3 weeks earlier in the year.

There are two things to caution with this trend though:

1> Be careful what you post. The same rules of posting photos to Facebook applies here – while the photo for”what my customers think I do”, depicting a wild beer-soaked party may get laughs around the office, it could damage your company’s reputation. Be witty, but bear in mind what could be misinterpreted.

2> Be efficient. What killed “Sh** suchandsuch people say” was that it became way too overdone way too quickly, often with poor production and terribly unfunny lines. If you’re going to get in on the fun, do it fast, but be effective.

Bottom line: Internet trends are like hair styles. Some will stick around and be used for ages, while others will fade away and become annoyances quickly. So before you grow your mullet or style a “Rachel”, take a keen look at “What I really do…” and other fads.
