Sometimes to a quite ridiculous degree. For instance I wrote
Bad Decisions for an MCU movie that came out this year, and in general I'm rather happy with it. It's not one of my top tier stories, but it's in high second tier I'd say. And in the few weeks it's been viewable, it's got 71 kudos (and an amazing comment from my recipient), which I'm more than happy with.
Last night I put up
Breathe in the Summer Air (You Are the Sand Between My Toes), which is a Kate/Yelena fic for the Hawkeye tv series, who had some fun interactions in an episode on Wednesday. And, well. Again, I'm not unhappy with the fic, but I wouldn't say that it's quite as good as Bad Decisions. In less than 24 hours, it's gotten over 500 kudos which is... Well, I'm certainly not complaining, but I definitely wouldn't say that's commeasurate with its quality.
Looking at my stats page, my fic with the highest kudos (as opposed to the fic with the highest kudos on my account, which was written by Louisa and definitely earned its 816 kudos the hard way) is a Jessica Jones fic which I seem to remember was also written very shortly after season 1 dropped and probably benefitted from a similar effect. (If not quite to the same extent.) The one after that (and now the new fic) is a Person of Interest fic that mostly benefitted from being written fairly early as regards interest in the specific pairing, back when it was purely subtext, but not from dropping at any specific point in time. (And, honestly, was a more solid fic than either Bad Decisions or Breathe.)
So, yeah. If you're looking for kudos, there's definitely something to said for capturing the moment.
