@donyi_polo: friend in your reputation comment you have written “But, name of the department itself indicates its nature of activities. If little description is added the post will be lengthy especially when there are several links in a single post.”
you are right but some time name may not be self-explanatory. In your post there two address for WB tourism so the area of focus of that website may be helpful. But I agree that well-known website/blog need not any description.
