I self snipped the last one, cause I don't want to argue this any more, but I will say I'm totally LMAO at your suggested use of <em> as what I would think is the right way to emphasize (dictionary definition of emphasis) keywords:
The em element represents stress emphasis of its contents... The placement of stress emphasis changes the meaning of the sentence...
Stress Emphasis in Liguistics
stress, in phonetics, intensity given to a syllable of speech by special effort in utterance, resulting in relative loudness... it may serve to distinguish meanings, as in English, in which, for example, stress differentiates the noun from the verb in the word “permit.”
