But in all seriousness, if you are in possession of utilizing your PC blog (i.e. you're of a specific tier) you should definitely utilize it from time to time. As probably one of a minority of users that actually does blog on a consistent basis, I find it as an excellent tool for a numerous reason: one is that is has exponentially improved my writing skills and the second being it has been a great way to vent out a lot of emotions that I've kept built up. You'll notice that after writing day after day on a consistent basis will improve your vocabulary, have you always proofread for grammar, and all and all make you a better writer. There have been numerous papers that I've written that I probably would not have gotten a good grade on if it wasn't for my daily blogging.
Of course, you don't actually have to blog on the insane level that I do. Even if it's something short and sweet, it will do wonders for you with real world implications, both on a mentally satisfying and skills level. As they say: practice makes better, no matter how you look at it.
