As one can see from my ever so slightly sour comments, my personal experience somewhat taints my view of the platform as a whole. Essentially, the people whose company I'd enjoy the least are most likely to have the appropriate profiles. I'm sure there are other things one could do with the platform, and I'm sure not everybody is like that. However, this isn't a balanced pro-and-con argument, it's a rant, so there is that! ;)
