This plugin will easily give the user the option to follow the category or tag of his choice. This is basically a widget based plugin, it will work from the time you activate your tag / category follow widget after you install the plugin. One of the conditions for this to work is that the user must be logged in.

Follow Tags & Categories

User's can follow specific Tags or category and show only those tags/category posts.

This widget adds a <a href="http://www.subtome.com/" rel="nofollow ugc">SubToMe</a> button to your WordPress blog. This button allows your readers to follow your blog using their favorite applications.
If the user clicks the button, then, it will load an external iframe with JavaScript. The iframe will show the user the list of their favorite subscription tools. Once they pick one, they’re redirect to it with your blog information.
The user information is stored in the browser, but is only accessible on the domain <code>subtome.com</code>, which is why we have to load the iframe.
No data is ever “leaked”. The whole <a href="https://github.com/superfeedr/subtome" rel="nofollow ugc">SubToMe code</a> is open source. Feel free to check it out by yourself.
