Note: this question is the one currently appearing as the welcome page example.
I happened to look at the welcome page today. It shows a example question and its answers. In my opinion the question chosen is not good example. Here is why:
The question (which was probably chosen for its brevity) is a rather open-ended question asking for recommendations of an open-source substitute for Wolfram Workbench. This question, while acceptable, is hardly typical. I further think it encourages new users to ask questions of the "Is there a thingy to do X?" sort, which are often not high quality questions.
The two answers shown are essentially link-only answers (again chosen for brevity, the actual question has other more thoughtful answers). I fear this will encourage new users to think that kind of answer is typical and desired.
I request that a well-posed question involving a coding problem or concerning a one of the subtleties of Mathematica that have answers that are not links be substituted.
I accept that it is incumbent upon me to suggest some alternatives. How about
Flatten command: matrix as second argument
What does the construct f[x_] := f[x] = ... mean?
What is a Mathematica packed array?
Partitioning with varying partition size
Replacement inside held expression
How do I extract the middle element(s) of a given list?
It would be necessary to do some editing of the above to use them as the welcome page example, but since the current example is clearly edited, I don't think that should be considered an impediment.
