My first post here at meta, so please be gentle.
I love the Stack-site. They are clean and it's very simple to get the information you want. Everything seems very thought-through. One thing I've noticed however is that at the right side of tags (on a question or tag-overview), there is no thousand-separator on the number of questions tagged in that tag.
See for example this question: How do I prevent the modification of a private field in a class?
On the tags on the right, I just see a bunch of random numbers. I really don't get any idea of how many questions we are talking about. I think it would be an improvement to add a separator here.
You can see the same at the tag-overview: http://stackoverflow.com/tags
EDIT: Or just see how
feature-request looks on the right side of this post.
