Yes, definitely. It's one thing to give constructive and helpful criticism with suggestions on how to improve something. It's entirely another to obsess over things you hate and rant and rave at anyone and everyone about it. It astounds me that there are still people who don't understand the difference.
But this is why I much prefer the Forums. It's more heavily moderated here, you can report troublemakers, and choose which threads to be (or not be) part of.
The article does touch on something important, though. The devs use Twitter to open up an avenue of communication with their player base, and since they've been more active on there, we get more information than we used to. But more and more Gurus are falling back into the background and going silent again, most likely because of the people who don't seem to be able to control themselves and their attitudes. I just hope that we can keep the Forums civil enough for them to consider more activity over here.
