The imagery is dark and unsavory which demonstrates the big bad city.
I like the modern technological theme throughout the story (especially the tweets) ...
I think you might consider trimming the narrative/dialogue regarding Libby's
tricks of the trade in order to keep the story moving forward.
All in all you've painted a glorious seedy, urban scenerio with great finesse.
Happy Holidays!

PS: loved the following vivid phrases:
"He felt a tremor in a far side of his brain. Words composed themselves, fitting and re-fitting into pegs"
"maybe a tweet—was brewing somewhere in his brain"
"with these new goggles the partial-words would gain personalities and squirm and scramble into a series, almost automatically."
"Libby smiled again, bigger this time, and it cracked the caked-on eye shadow from a night-or-so before that was clothing her eyelids."
"The thoughts he was having made it difficult to compress the process into 140 characters, an aphorism. He wondered what Hermann Melville would have done if he was faced with the challenge of expressing the ideas behind Moby d--- into a sentence or two. It would probably be a series of tweets. There were a lot of tweets in that novel, he thought."
"They were neurons firing from one building to another like synapses, each a pulsating bit of data and information spreading its numbers around like disease"
