Do I have Aspergers if I fit the description of one almost exactly? The author seemed to be describing me.. I am pretty socially capable and I can look people in the eye, so I don't know.
Strictly speaking, when the DSM-V comes out, no one will have Asperger's _per se_ since they've removed it (under the assumption that people will either be classified under the revised definition of Autism, or not at all).
Under the DSM-IV, one of the criteria reads: "(III) The disturbance causes clinically significant impairments in social, occupational, or other important areas of functioning." -- generally, it's up to a psychiatrist's professional judgement to determine this. Sometimes it will be obvious; sometimes it won't. Don't self-diagnose.
The main reason why Aspergers is no longer used as a diagnosis is because it's a fuzzy area on a spectrum, not a clearly delineated thing.
So yeah, you could be somewhere along the spectrum. Or you could just have certain personality traits that are somewhat like it. Be careful with labeling yourself unnecessarily. It can be comforting but also limiting.
