Well, setting the default-left-margin-width et al. like this looks a
little strong.   I would have done the reverse, left the default at 0,
and added hooks to the modes I usually use AND I want to have margins
with.

Probably the problem you have is that newsticker uses actuall various
modes for its various buffers (I assume, it doesn't seem to do much
here), and it happens the buffer where it displays what you want are
in modes for which the hooks you defined are not executed.  You can
check the mode of a buffer by typing M-x major-mode RET in the buffer.



But consider doing the reverse, leave the default at 0, and set
left-margin-width and right-margin-width to 20 in hooks specific to
the modes you use for your daily editing (eg. text-mode-hook).
