Note that I'm writing this 2am because I just returned from Lebowski Fest LA, so my judgement may be warped by both the lateness of the hour and my personal admiration of The Big Lebowski (henceforth abbreviated as "TBL")

I wouldn't use those names in a work environment, although if I came across them already being used, I'd probably see them primarily as references to TBL and not as references to porn. And remember, both LogJammer and Treehorn are both mocked as completely ridiculous in TBL, and not admired in the least.

I guess what I'm saying is that if you're trying to gauge how offended to be, consider that any offensive nature of the names were almost certainly due to tone-deafness rather than maliciousness.

(In a non-work environment, I'll be dropping potentially crude TBL references all the time, because it's a hilarious movie. Say what you like, at least it's an ethos.)
