One can put tags on their post/s and that page dedicated just to that Tags. If one want to find out what people are talking about on a certain subject or topic one can go to that page but that information must be covered in the post.
If one wants to see all the posts – for example – wordpress go to Tag Surfer page and enter tag. Every time one can login and check all the posts which are tagged with ‘wordpress’. If one does not want to follow a tag then click X against that tag which will remove the tag with all its posts.
