OK everyone take a deep breathe now.
Yes it is important for people to give advice. But it is also dangerous for someone with little experience to give wrong advice. There are many new beekeepers on here, and it is important for them to participate so it isn't the same people having to answer the same questions over and over. But if you have no personal experience with the methods you suggest, it is also key that you add a disclaimer to warn the requester. Something like, "I've never done it this way, but here is why I think it would work" or "I'm a new beekeeper, but from what I have learned I think...."
Just giving broad motherhood statements, that are flat out wrong, with no justification is not being helpful. It is easy to make such statements when your bees are not at risk. But if you got burned by someones wrong advice, you would not be very happy.
So let's make our knowledge level clear when commenting on things we have no personal experience with.
