Oh, anywhere from 35-85% of my day is actual work, depending how busy the library is and how many projects I have going on. But I spend alot of time either sitting at a public service desk or loading builds and software onto PCs at my desk, so I can spend a good amount of time posting while still doing work. I often ahve 2 or 3 PCs up and running at any given time, so my personal machine ends up being an email/ENWorld/music box while I work on the others. Of course, there are some days where I have no other projects going on, so those tend to be on the less productive end of the scale, where I'm physically cleaning dust out of PCs and straightening up my workspace, those days I post and surf a heck of a lot more. And there are the few (thankfully) days a year where we are loading builds onto the public PCs in all 14 libraries, and I'm not at my desk all day for several days in a row. Those days it's 100% work.
