Most of what I watch in terms of SC2 is in streams. But when you compare certain SC2 streamers together, there's a huge difference.
Some of the new streamers just don't know how to stream. And by that I don't mean stream high quality stuff, because almost everyone has it these days (except for me ).
Instead, it's that lack of personality in the streams that make them apparent. I can't tell you how many times I've looked at the featured streams and I say "Huh? Since when was this person a featured streamer?"
And then when I proceed to watch him/her play, it basically is the exact same stream as some other person's stream. Just a little bit different music, and a little different of the same dry commentary. Sometimes there's not even that.
If you're watching the streams for just game after game of intense high level play....I guess that's fine. But as far as I can remember, streams were far more than just gaming. It was a personable experience and an opportunity for the viewers to meet someone who's contributing to the community.
