I don't think it should be closed. I think we should look at the bigger picture. Open Data is quite focused on the "open" part, so on the release and collection of data. There was a short discussion talking a bit about it.
There is a growing data.SE project, SO and some other projects probably have many questions on the topic of analysing and manipulating data (even though I don't know how wide the scope of your "use" is).
But I agree that there is a large part of the questions that will cover data collection, and it should not pollute the rest of the site. That's why we should tag them properly (and maybe have a template). There is another discussion about it.
