HN is full of "nerds" and nerds (edit: stereotypically) love Sci-Fi. It's also full of conversations about work/office-related topics. So, Sci-Fi + Office Space being topical here makes sense in a very generalized way. At least IMO.
The comparison to Office Space is specious at best.
I got the same impression. I find it strangely reminiscent of a sponsored reddit advertisement.
Sorry about that. It was, as jjulius said, the combination of SF and "office" theme that I thought would fit.
