From my own very biased experience of having lots of close friends and never a dull moment, all whilst working alone for most of the day in my apartment... perhaps I do have low social skills, but it doesn't seem to affect me in a negative manner.
I choose to know a small number of people very well. It doesn't interest me to know a large number of people hardly at all.
If I wanted to "up my social skills" and "gain tons of 'friends'" I could easily do that I would think. Simply by mimicing the flaky personality described in the article and sure, everyone loves a yes-man.
