It would be a little extra work but we don't want to impose new rules. Most people, specially newbies don't read these guidelines. We don't want to miss any good content just because an author used the tag #recipe instead of #food.

Our aim is to support the quality content and for that we want to facilitate authors to have some freedom with tags.

There are no specific tags but people should know that relevant tags are what make the post accessible. So completely off the topic and complex tags shouldn't be used at all.
