You can make any
site more dynamic and interactive by the use of opinion polls.
These can be used
to provide addtional interest to users, in that they get to express
their own opinions (we all like this) and you can allow them to see
the results too.
As well as using
them as points of interest, you can use them to get information from
your visitors, as simple market research tools.
If you refresh them
from time to time, you can keep your site looking current and topical.
You can get various
off the shelf, free solutions, although these may require the display
of advertising. For an inexpensive solution you can run on your own
server, check out: Poll
