I do like microblogs, however I would encourage students to follow organizations like ASHRAE and AWS the reason is for reference and bettering their skills in HVACR. A lot of knowledge the how, when, where, and why; is what I think the books is about. This information is most time relatable to theory some 30 to 40 years ago. The theory is correct but the change in technology is growing at such a rate that to stay on top one must stay in the area.
