If you click "Aquaria Central" on the top nav (http://www.aquariacentral.com/), it takes you to a page that posts a random poll. People can then respond, although not vote, in the poll. A different poll shows up with each refresh.
That's what I've been doing, OG, and seem to get majority old ones. Not a complaint, as I find them interesting and usually pretty educational. Just an observation!!
