[tag:Point] has seven questions with almost as many tag definitions.  It has been used to mean restore point, mounting point, wireless access point, and location on an image.  There were no examples of data point, although that would also fit.  The tag has no definition and its varied usage eliminates any value as defining a category.

Recommendation: replace this tag with more specific ones.  [access-point] and [wireless-access-point] already exist.  Create tags called [mounting-point] and [restore-point].  Tags related to data points or locations on an image are probably not necessary and in the absence of a [point] tag, people will select appropriate existing ones.
