Is it just me?

Could it be that the word literally is making a comeback?  I thought it was slain by the rise of impact as a transitive verb, but in the last week I have heard or read the following constructions:

She literally walked by me...

We are literally serious about this.

The athletes' village in Delhi is literally unhabitable.  Toilets are literally blocking up, and there's cause for concern about hygiene.

I suppose we ought to be grateful that Mister Rabbit is not virtually abandoning the project of parliamentary reform through his intransigence over the pairing of the Speaker's vote in the House of Representatives.  No.  He's literally being obstructive.

The combined effects of PR and politicians have a powerful influence on how people use hyperbole in their day-to-day conversations.  You know when words such as impact, illegal, literally, and so on, have reached new or renewed currency by their rapid-fire appearance in the snippets of conversation one hears on the train or in a cafe.  By the time it makes it to the opinion columns of your newspaper of choice you know that the rot has literally set in.  I saw a sentence with a double literally today.  One could weep in despair.

This verbal tic literally grates on one's eye and ear, attesting to the palsied imagination imagination of the one who utters it.  Unfortunately, management types and politicians -- who would normally pass as literate, thinking people -- seem to be the first to take up the word of the moment.  There must be a hormone which responds to the recitation of the word, such is its growing recurrence.  Could it be that some people are (unknowing) serial buzzword junkies, repeating the same thing over and again to keep the endorphins flowing?  Is it possible to die of a buzzword overdose?
