Since it may not be obvious, questions like http://www.quora.com/Communication/If-you-had-a-conversation... won't show up in feeds unless you follow the Joke Questions topic. There are several other topics applied to content that doesn't have broad appeal like Quora Community. The alternative is to actively delete questions like this but the reality is that the site is too active for that to be feasible, also, regular users aren't doing the same kind of content curation that they used to. Questions used to get quickly edited or flagged, now they just sit there until they get activity and users just answer them without fixing grammar, punctuation etc... so part of the problem is that the number of people who care about curating content hasn't scaled with the over-all population.
