Sorry man, still the same person here. You may use any tag you want inside the text of a post but it does not create an instance of that tag being used on the blockchain. Kind of how the above post listing all those tags does not actually tag that post with all of them.

It links to them, sure, but it doesn't add to their use. Linking your posts together with tags won't work either. Months ago I used to tag my posts as #guiltyparties. Currently, if you click on that tag, you'll see that nothing is tagged there. That's because after a while, older posts cease to be pulled up. The query to pull them is too challenging/lengthy to execute so Steemit or any other service/site has a cut off.

The best way to ensure your content can easily be found by your followers is to keep your profile clean. That means not resteeming other people's content unless absolutely necessary.
