This is the page first-time posters see:
On the right it says,
Is your question about Mathematica?
Can we change this to the following?
Is your question about Wolfram Mathematica?
Is your question about the software Wolfram Mathematica?
(Including emphasis on Wolfram Mathematica to highlight it as the software's name.)
My hope is that this small change will reduce the number of off topic questions which are really about math. Currently we have several such questions every day. Many of them are of low enough quality that they don't even get migrated over to https://math.stackexchange.com/
Will this change have any effect? I don't know, but I think it doesn't hurt and even a little improvement would be useful. It is clear that many new posters completely ignore much of the information given in the first-time asking screen I showed above, so it probably won't have a large effect. But every little bit helps.
The idea was brought up by Chris K in chat.
As a side note, there was a Meta.SE post about the great need to guide new users better: https://meta.stackexchange.com/a/285903/164803 Hopefully that project will bring better results.
