A fellow animeblogger Josh, who usually takes his enterprise way too seriously, ran a poll on what he should watch next.
When a blogger does this sort of thing, it serves two purposes: to have some material for readers to relate to (and comment upon), and to get some series to watch. A bare poll is a bad way to do either. An article would at least show that the blogger did his homework and thus make it more likely that readers do the work of replying. But even if they reply as-is, the resulting commenting without any knowledge where the individual in question comes from degenerates into a contest of favourites, which is not going to produce any meaningful outcome.
For an example of how to do it right, check the old posting at Kaedrin. Mark certainly put more effort into it.
