Because generic view uses a queryset (which it clones at the very
start causing your original problem) the only way (I can think of)
would be to write your own Manager which returned Post objects
annotated with your new flag. Never played with custom Managers yet so
I could be talking rubish...
Another equally complex solution would be a custom templatetag since
it would be in a position to see both the object and the context from
(which it could get last_seen).
If there was an {% ifgreater a b %} tag you could use that. I could
not find any matches in google for that but you can use the expr tag
(non-standard) to the same effect.
See http://code.djangoproject.com/wiki/ExprTag
I think you would need to pass last_seen in via extra_context and do:
{% expr object.topic_modification_date > last_seen as newflag %}
{% if newflag %}
<strong>NEW!</strong>
{% endif %}
