I rarely use MSE and so I don't have a good feel for what it's like overall. I was slightly surprised by a recent comment by Christian Remling which characterizes MSE as a "homework factory with noise/content ratio $\approx \infty$" that is no longer even a "moderately reasonable site." Seeing this comment made me wonder whether the common practice on MO of suggesting that a question be migrated to MSE needs to be re-thought. If MSE is a complete mess of a site (I'm not sure it is, but let's suppose for the sake of argument that it is), then directing people to it seems like a bad practice.
I would be somewhat reassured if someone could show me some statistics, demonstrating that a high percentage of questions that are migrated from MO to MSE receive answers that are subsequently accepted by the person asking the question. Are there any such statistics available?
