You may have noticed that, while the blogosphere and RPG forums are lit up with discussion of D&D Next, I have been pretty silent. This is not an accident. I didn't sign up for the playtest. Yes, I'm curious as to what it will look like, and it would be nice if it were close to the kind of game I'd like to play (or at least within easy modding distance.) But I don't need it, so I don't feel like getting involved.
I've seen a couple people compare the open playtest is like the presidential election: if you don't vote, you have no right to complain. I could say a lot about that, but I'll stick to this: Products are not Presidents. You don't vote for a product, except maybe with your wallet, and even then, you can choose not to buy a product if it's unappealing.
Of course, my complaints about a product are generally limited to explaining why I don't like it when somebody asks, or comparing it negatively to something I do like, when explaining why I like it. Maybe an occasional snarky comment when someone brings it up in conversation. I don't devote a lot of time to stuff I don't like.
