At first I thought my question might be a duplicate of View questions with the same tag across multiple SE sites, but it's different. In fact it's the reverse.
Most of the time users encounter with the problem where to ask a certain question for example there is the tag
remote sensing in GIS, Space Exploration, Earth Science, so someone who wants to ask a remote sensing question may be confused where to ask the question. Since cross-posting is not allowed on Stack Exchange he finally will choose one of these sites and most likely his choice will be GIS because of the more traffic of the site while Space Exploration was a better choice for that specific question.
We have the same problem for the tag
OpenGL in Stack Overflow and Game Developement and for many other tags that are available on multiple Stack Exchange sites. The OP wants to show his question to the largest audience available and he often cross-posts and downvotes start advising him not to ask the same question in multiple sites.
I think a good way to solve this issue is to include the question with the same tag in multiple sites. For example, consider someone who is active on GIS.SE and asks a question with the tag
remote sensing there then this question might be included (or just viewed) on the two other sites and when someone answers the question in one of these sites, that answer should be included in the other two too.
Maybe you ask
then how will we score the questions and answers then?
Suppose that the question was asked on GIS and included on ES. But the answer was given on Earth Science and included in GIS. Then each upvote to the question will be added to the questioners' score on GIS and each upvote to the answer will be added to the responser's score on Earth Science.
I can think of following benefits using this approach already, but maybe there are some other advantages and also disadvantages. I don't know. It's just an idea and a discussion.
- As I said, the question will be exposed to the largest available audiance that might know the answer and so the questioning and answering process will be even faster.
- User's confusion about where to ask will be removed and the probability of cross-posting will decrease.
- As I said, most of the time people choose the site with the highest traffic as the appropriate one (here GIS) and this diminishes the beta sites' probability of success in reaching their critical number of questions and graduating. So this approach will intensify activity on beta sites.
- Most of the time moderators of old sites are concerned that the new proposals might tend to drain audience from their site and will disperse the users (For example Remote Sensing and Photogrammetry proposal might drain audience of GIS, earth science and ... ). But this approach will minimize this worry.
This way Stack Exchange will be converted to a big site that virtually has different sections. Each expert will be active in the section that is most related to his expertise, but he will also see what is related to him written in other sections of the site. This way each community will have its own site and its own brand and will help other communities in other parts of the site.
P.S. As I've said, here the problem of remote sensing and photogrammetry is that it is an interdisciplinary subject. Each sites Physics, Mathematics, GIS, Earth Science, Space Exploration, Aviation, Cross Validated, Electrical Engineering, Engineering, and Open Data contain a part of remote sensing, but they do not cover the whole of it. I'm trying to build a place and gather all remote sensing researchers there to have a focused site about this wide subject.
