I agree with everyone else above.
I've worked in Tech for a few years, and I identify fully with your Rant's, and I just Love Guru's World in general. I think it's mainly the people who you write about - those with not too much idea, and very little patience - who tend to get offended or upset.
I think Rants a a perfectly healthy way to express certain things, and also a great way to get various points across. Most people are going to remember something better when they've Laughed at it, or growled at it. People seems to remember better when emotion is attached.
Please don't stop the Rant!!

Just my 2c
