Categories help you find the information you need faster and help you stay up-to-date with content most relevant to you.
On the Home tab you'll find a module to subscribe to categories. This means you'll be notified when a question or answer has been posted with this category.
There are three ways to use categories to stay up-to-date and organized:
Subscribe to categories to be notified when questions with that category are added
Filtering search results or the by category
Assigning a category to a question before posting
