Hi Roland, as far as I can see you aren't using the templatetag correctly
and actually never call it.
{% load %} is called with the name of a templatetag file to make
available all the tags in it. From there you would need to actually use
the tags.
Also, you either need to call the tag within teaser.html or have the tag
render teaser.html. What it looks like you are trying to do would do both
and result in an endless recursion.
My recommendation would be to make it an as_tag instead of a simple tag.
Here's an example of an as_tag from Mezzanine,
https://github.com/stephenmcd/mezzanine/blob/master/mezzanine/blog/templatetags/blog_tags.py#L54
and the way it is used,
https://github.com/stephenmcd/mezzanine/blob/master/mezzanine/blog/templates/blog/includes/filter_panel.html#L4
.
Then include teaser.html and within it call the as_tag and render the page
it returns.
Also, maybe take a look back over the templatetag docs,
https://docs.djangoproject.com/en/1.8/howto/custom-template-tags/#simple-tags
Good luck!
