It's not "lazy," it's just standardized. It's continuing the precedent of using 3-letter abbreviations for show subtitles. Which is the official practice of Star Trek's own makers, so it's pretty bizarre for you to use it as an excuse to insult your fellow posters' alleged laziness.
It *seems* lazy for the standard to be adopted, not that it actually is lazy for anyone to do so. The historical reasons for the adoption are well-documented (Okuda Chronology standardization of the then-four shows as a reference citation). I'm an old MA-er, so I used three-viations for over a decade, and understand their utilization for citation purposes. Although, Memory Alpha doesn't really need it anymore, since they've long since templated their citations.
Any standard, or precedent, should always be questioned, for a variety of reasons. Since we're likely coming up on a majority of shows with short one-word subtitles, I strongly feel the old practice is getting in the way of honest discourse. It's causing unnecessary arguments (especially on the Discovery boards where I first noted this), and, frankly, there is zero need for the differentiation when "Kelvin" works much better unambiguously than "KEL" or "Enterprise" than "ENT" or "Voyager" than "VGR".
I used buzz words like "stupid" and "lazy" out of, perhaps, frustration that none of this is ever taken seriously. But I was very careful to address the situation, the abbreviations and not any poster or user of them. Or, at least I thought I was careful, until I was insulted by my favorite author. *shrugs*
