I have developed a particular fondness for the word "muscular," and I think it is a great way to describe last word art. Perhaps the technique or framework is not novel, but the result it achieves is what ultimately makes it longer lasting and impactful. Yet, I think today's short-attention span with regard to which technologies are "trending," is a good thing. If there are enough ideas out there that are that enticing, then they certainly shouldn't be overlooked. It's like we're in the sketching brainstorming. We haven't explored everything enough to decide which ones are worth really diving super deep into.
I see Homestuck as an example of both first and last word art that has fallen victim to changing times. It is essentially a pseudo text adventure on the internet. The webcomic makes use of gifs, flash animations and games, and convoluted narrative paths to follow through hyperlinks. It wasn't the first of it's kind, but I believe it's one of the most significant because of its scale and fanbase. And at the time it was a pretty novel idea. But today, the time for that kind of sensibility and aesthetic has passed, as evidenced in the direction Homestuck itself is moving now, toward the sleek indie game scene. In that way, I think culture almost holds technology and art hostage, because these things (usually) require an audience, and if you're audience is moving in one direction, how can you not follow them? Perhaps sometimes new technology holds itself hostage in this way, sending the masses in one direction, and being compelled to follow it thereafter.
