In my case, part of the reason I say very little about work is my employer is a bit paranoid about trade secrets getting out. I do occasionally post about work, but the posts are mostly devoid of any technical details and center around "office politics" more, plus they are always locked.

The other reason is people at my company can very easily get consumed so they work way way way too many hours and pretty much have no life outside of work. To keep myself from getting pulled into that sort of lifestyle I try to keep work and "life at home", which includes my dreamwidth account, segregated for the most part.

Of course, I do fit the mold of "women are less interested in the technology behind the thing (e.g. they don't care much if it is written in Perl, Python or Java) and are more interested in how can a tool help them to get their job done" in that programming to me is typically a means to an end but in my defense I'm not a programmer by trade - my work in another area of technology instead. However, I do find joy in writing scripts at work, not only because of what they let me do, but because of the improved efficiency and the instant gratification of seeing it work right away.
