This question already has an answer here:
I just posted a question related to Capybara, and after tagging it as such added the 'ruby' tag as well, since (of course) Capybara is used from and written in Ruby.
Although 'capybara' was the first tag, Stack Overflow chose 'ruby' as the primary tag to display in the title. Why is this? What are the effects of this? Is there any way to change this other than just removing the 'ruby' tag?
Because Ruby is a much more general category than Capybara, it seems to me that making 'capybara' the primary tag makes more sense and will be more likely to make it stand out to the right people. Is this correct? But on the other hand, a good portion of Rubyists know something about Capybara, so I'd like to keep the 'ruby' tag there too, so they notice it too.
