Well, another way to look at it it is that with 2.68 being the lowest score and the range going from 1-5, people seem to generally be relatively happy about their TrekLit
Though it's interesting to note that many of the poll options may be relative rather than absolute, i.e. "Above Average" might not satisfy the question "Is this a good book?" but only "Is this a good TrekLit book?" depending on the reference frame people adopt while voting. So technically you probably can't really derive a general level of satisfaction with TrekLit, except that "Poor" is, well, poor in an absolute sense, so general dissatisfaction
would be visible. Then again, it's probably moot - people who generally dislike TrekLit are unlikely to vote here. So TrekLit-relative poll options make good sense.
