One of the rules of thumb about decision-making that’s been helpful to me is “If it’s not a ‘Hell, yes!’, then it’s a ‘Hell, no!’.”
Feel free to try that one on for yourself.
I offer it here because it seems apt for your comment. Your post has me wondering if you’re trying to talk yourself out of buying it (which is fine) because:
there really isn’t any field that we know 100% what fields are in it. And didn’t Dream recently pull a field because he was tired of people using knowledge of what was in that field in order to reverse engineer copycats?
So, you’re free to set your criterion for your decision-making. Maybe you’d find it more helpful to you if you set a more reasonable criterion–such as “Does this field do what it says on the tin?” (It does), etc.–for your decision-making?
