title: Website version numbers - useful or pointless?
body: <p>My <a href="http://www.markembling.info/" rel="noreferrer">personal website</a> and others which I am involved with) display their current version number discreetly in the footer or some other area of the site. My question is whether this is useful information to visitors or whether its just textual "noise".</p>
  
  <p>It is worth noting that the version number is the version of the software (not the data within the blog or whatever), so is irrelevant from a "how old is the content on this site" perspective.</p>
  
  <p>Since only one version of the site is active at any given point in time and it is not a redistributed product, does the version number serve any purpose? I understand this is somewhat of a subjective question, but I would like to gauge opinion on this to guide future decisions regarding version numbers and their relevance.</p>
