Tagging is central here in Tagalot (which you mihght have guessed already). While you most certainly can ignore tagging alltogether, we'll still like you anyway, it certainly opens up for new possibilities!
Tagging a post here in Tagalot means that you can find your content again easily, plus everyone else can find your content! Tags on Tagalot have their own pages, and relations. You can discuss them, see what others are writing about that particular tag and things like that. By using tags, you set yourself up to find new content about what you are interested in!
Did you write something about cooking? Great, we love cooking as well! So we'll meet and discuss it under the tag "roasted beef", or "outdoor grill" or whatever tags you think fits your content!
