"Mashup" by Floris M. Kleijne appeared in Daily Science Fiction on January 25, 2013. "Against his anachronistic best friend's warning that he'll be bombarded by ads, David purchases the equivalent of a hyped up iPhone with an AI that makes suggestions to the user based upon knowledge about the user gleaned from the ambient web--and it appears his friend may have been right when the AI suggests a purchase that the user would never even dream of making."
Whew! That sure is a rambling summary sentence that I just wrote there, but this excellent story by Mr. Kleijne has a lot going on. Techno-nerd stuff, philosophy, a possible kidnapping mystery, and, above all, romance! I read tons of spec lit, so I (unfortunately) saw where this story was headed early on, but I would not say that the plot was predictable. I daresay most readers will be in for a pleasant surprise by the end of this clever tale. 6 out of 7 rocket-dragons.
