Once again, I've gone through and compiled the last 100 posts for a word cloud. Someday I'll figure how to save everything at once, instead of copying and pasting from blogger to make an almost 60-page file.
"Environmental," "field," and "work" are always big. I think that "drilling" and "safety" are a little more prominent than in past post compilations.
For comparison, here's the previous word clouds: 500, 400, 300, 200, and 100.
