Flattery?

IMITATION IS THE SINCEREST FORM OF FLATTERY - "Usually said ironically when someone tries to gain attention by copying someone else's original ideas. Coined by Charles Caleb Colton in 1820 in his 'Lacon.' First attested in the United States in 'Malice' (1940) by E. Cameron. The adage is found in varying forms." From "Random House Dictionary of Popular Proverbs and Sayings" by Gregory Y. Titelman (Random House, New York, 1996).

Like I said in an earlier email, "Be original...please."

And if you happen to be doing something that seems trendy, or a word I prefer to use, which is timely - do it different and do it the best.
And if you are going to jump on to someone else's idea, at least give them credit of some kind, either publicly or privately.
