Could somebody please explain why [[Water chestnut]] is a disambiguation page (with, in my opinion, neither splitting article really doing a good job of describing the tuber that most English-speaking people are familiar with from either a grocery store can or their local Chinese restaurant), while [[Corn]] (which redirects to [[Maize]]) is a really nice article that talks about the corn we all know and love, while having a convenient, unobtrusive "disambig" flag at the top?
Doesn't the water chestnut deserve a little better than this confusing disambiguation page? It's a pretty common food. Does the Wikipedia community really expect users to find their way specifically to [[Eleocharis dulcis]] to get a half-decent write-up on the water chestnuts that many of their recipes call for?
