Februs:
It doesn't affect me personally as I don't have any stories loaded but I think the site in general is far more interesting and lively with a decent number of comments getting made.
That is absolutely the case. As is having the Forum. And the popups.
To read in a vacuum is ok, but it's better to read in (and write for!) an active group.

In addition, a month or two ago we introduced a feature which displays the announcement banner (with a reminder to comment) to non-commenters which also seems to have helped a lot too.
Does that mean I can stop performing that function?
