How nice to see my favorite show celebrated this way.
Yeah, really what articles like this, and other recent ones like it, mean is that DS9 has staying power, both on its own merits, and on the influence it has undeniably had on the genre as a whole. The extent of that influence can be debated, but it definitely had and continues to have an impact.
TOS will always be the most influential, its influence is just taken for granted at this point.
Anyway, as you say, as a longtime Niner, nice to see this type of article being written about the show
