I was thinking about building some kind of network or large website, so I was reading a lot about the Multisite option that came up last years. I still have some question marks on when should I use it instead of a single site and when I shouldn't. The thing is that also on a Single WP site, you have different types of sorting, organizing, differing, etc:
So I'll give an example and I hope someone can clear it down:
Let's say I am building a site about car companies. The companies are Ford, Toyota, BMW, etc. For each companies I have different articles about different subjects: New technology, specific stock market news and company's reports, company's commercials, best models of the year, etc.
What would you do?
Multisite option: Ford, Toyota, BMW - Sites in a multisite network Different articles' subjects - Categories in each site (these categories will be duplicated on each of the companies' site).
Single Site option: Ford, Toyota, BMW - Categories (or taxonomy?) Different articles' subjects - SubCategories (these subcategories will be duplicated on each company's category).
I did not include the post-type option because from what I understand, it's more for cases where the type of posts is totally different: video posts, image posts - but maybe I am wrong and that's an option too.
One more thing I forgot to mention but I guess it is possible to do both ways. I think it will be more logical if the address structure will be like this: ford.site.com/ArticleSubject/path/to/post...
What is your opinion? Many thanks!
