or being facetious but I'll post a reply anyway.
'Meh' is simply one of those internet responses that represents something akin to boredom, like when someone announces a 'new kit' that was actually announced three weeks ago. Another person might be thinking "meh, that's old news. Scroll down five threads" and that person is expressing that clicking this was almost as big a waste of time as formulating a well thought out reply.
Or maybe more appropriately in this case, when someone posts topics with titles like 'Holy grail photo!!' only to find some very well known, common picture that's been published in three different books previously, or 'Ultra rare conversion!!' and posting something so uninteresting like a modern day, back woods, custom made redneck vehicle that has nothing of interest or usefulness in the grand scheme of things here.
It may not be 'technical' but it certainly is scientific.
Build how you like, like how you build.
