Non-notability and trivia seem to me to be the whole point of a universally editable internet encyclopedia. If I wanted to research so-called notable subjects, I'd use a proper encyclopedia written and edited by paid professional experts; if I wanted to research anything to do with so-called non-notable subjects (like much of contemporary popular culture) then the only encyclopedia in the world likely to have an entry for a webcomic is, and should be, the wikipedia. The notability requirements defeat and frustrate the natural utility of the wikipedia as a reference.

Imaging with the shutter closed measures a different source of noise known as dark current (thermal noise of the ccd will cause a small number of free electrons rather than those freed by incoming photons). This noise is proportional to the length of the exposure, unlike readout noise which is a single constant factor.

As far as I know (I'm just a theorist), it is impossible to remove readout noise, since it is affected by the actual distribution of electrons on the ccd image. Someone who actually deals with astronomical imaging should feel free to correct me here.
