I think the topic of this discussion is fundamentally flawed. "WAMP questions" seems to be a general category of questions that involve WAMP at some level, but this category is far to general to say that every question in it does or does not belong here.
Instead of trying to make such a general assessment, what you should do is continue to judge questions individually on a case-by-case basis as per the criteria for a good SO question. It does not matter if it involves WAMP or not, it only matters if it's a well-formed programming question.
Questions like the following would not belong here:
- I am having trouble installing WAMP on Windows, can you help?
- Do you like WAMP?
- Please write such-and-such program for me. I am using WAMP.
Questions like the following would belong here, IMO:
- I am using WAMP. I have wrote the following minimal test code and I am getting a MySQL authentication error. I have tried setting the following options, but the problem is not resolved. I am not sure if it is a configuration error, or a problem with my DB connection string. What is going on?
- I am trying to configure WAMP to include such-and-such PHP module. I am running into issue X. I've tried the following things, which I found via Google, and am still seeing this error. How can I configure this? (Specific, well-formed questions about programming tools do belong here.)
- I am having issues with some SQL query. I am expecting the results to be X but I am getting Y. I have tried Z. I am using WAMP. What is the problem? (In this case, the question isn't about WAMP, and the poster included it as an irrelevant detail.)
It really just has to be case-by-case.
If you spot questions where WAMP is irrelevant, that does not mean the question doesn't belong here. That simply means the poster believed WAMP was relevant. You may correct the poster in a comment, or in your answer, or edit their question if it is appropriate. If somebody asks a question and erroneously mentions WAMP, it could very well still be a good question with a useful answer, and there is no reason to discount it simply because WAMP was mentioned.
It is the same thing with any poorly tagged question, or any question where the poster mentions something irrelevant. It's no different than somebody saying "Why doesn't
int x = "hi"; compile? I am using Java 1.7." -- that's not a case for a blanket ban on "Java 1.7" questions, it's a case for clearly explaining why it is irrelevant in the answer.
As for how to deal with it: There are many ways to get rid of a poor question. You could leave a comment to the poster explaining how to improve it. You could vote to close it. You could flag it for moderator attention. You could downvote it in the hope that if enough people agree with you it will prompt the poster to remove/improve it. Simply saying "WAMP [or whatever topic] questions aren't allowed" won't actually do anything; it won't stop the questions from being asked. At best, it will stop people from tagging them as "wamp", thus making them harder for us to identify.
In a meta sort of way, this very discussion has a similar quality - WAMP is, if you really stop and think, irrelevant. You list two concerns, and WAMP actually has nothing to do with those. The true concerns are in general: questions that mention irrelevant details, and questions about software configuration that are better for Server Fault. Specifically mentioning WAMP is, ironically, an irrelevant detail. Your concerns are appropriate for any topic.
