I'm going to be starting up a blog I think - focusing on some of the things I do at work. I'll be doing this from home, but sharing experience that I've gained on the job.
I'm a salaried employee, and I want to make sure I don't go afoul of my employer. How do you think I can best segment this and prove that none of the work is being done at a time that conflicts with my salaried respomsibilities?
Can you accomplish what you want with the blog without tying your real name to it, and not mentioning your company by name as well?
Employers can be kind of nervous about this sort of thing. If you name yourself and/or the company on a blog that you control, that can be seen as a liability if you leave on bad terms, because then you are free to bad-mouth the company on the same blog.
As opposed to a blog managed by the company, which they can immediately cut off access to.
It seems like a productive use of your time -- reflecting on how you solved problems at work can reinforce both the usage of the tools/methods you used as well as the critical thinking skills that led you to the solutions you found. I do things like this at work all the time, though I don't publish any of it on the web.
If I were in your shoes, I would talk to your supervisor about your idea and ask them if it would be ok to spend, say, a couple of hours per week on this. It might be useful to share it with colleagues and encourage them to do similar things in the interest of open knowledge sharing, something which I've always felt was lacking in both academic and industry settings.
