  My first day off! I have no class on Thursdays (and only one tomorrow) so it's nice to wind the week down this way. No big plans for the 3-day weekend, except perhaps to organize myself and maybe go to the beach, if the mood strikes me. So, my Communications Law & Policy class is very interesting, to me, but it's the first time I've been in a class in law school where the "Know-It-All" contingent has made a showing.
These are the people that in a technology-oriented (or even just related) class, cannot help correcting the professor or injecting "helpful" facts into the discussion. I find this annoying. I believe it's a by-product of two things: the social ineptitude of many who have worked in the technology sector, and the rapidly evolving nature of technology itself. Because of the speed at which technology advances, it's very hard for any teacher to ever stay completely on top of every development. It's much easier for a student who studies the field simply out of interest. The end result is when the professor says (merely giving an example - none of this is testable material) that AT&T broke up in 1983, someone immediately (and usually without even raising their hand, which is another issue) says "Actually I think it was 1984. " Of course that doesn't matter at all to the professor's example, but it gives the geeks a chance to show their prowess in the area. This may only be impressive to other geeks, but speaking for the group I can honestly say it just annoys the crap out of me.
In general, this doesn't happen much in law school because unlike some undergrad teachers, every professor is far more informed about their field than any possible student. But add a little something about the Internet, or computers, and all of a sudden a geeky minority feels emboldened to add their unimportant and irrelevant 2 cents. And that's my 2 cents! But notice I didn't subject an entire class to it. That would have been lame.
