As Comixology and other digital platforms slowly grow as an alternative way to buy comics outside of graphic novels, back issue bins and scans of nefarious provenance, what would you want to see put out there in digital form? Digital comics are unique in that page count and sale figures are irrelevant, so far as putting the product out there. (Of course, one must be reasonably aware it will sell decently when restoring the original copies and placing it over into the digital format to make it worth their time.)
It provides an opportunity to put one-shots, two-issue or three-issue arcs out there in an accessible form or more niche stories, which would otherwise only be resigned to the more completionist Epic Collection or Omnibus format. A lot of their new releases are tied into trade paperbacks, which is a shame because it could follow its own pattern.
So what's absent which could do with a digital release?
For one, a lot of Annuals aren't on there, which for some reason Marvel have chosen to group in with the main series. From a narrative point of view it makes sense, but otherwise it's hard to browse through.
Fantastic Four have substantial gaps too.
One thing I would love to see is the FCBD given a proper place online. Although some are reprints, the original stories become a little harder to find or relegated to the back of a TPB, even as a short vignette. The last two years Comxiology has been adding them within a month of the day itself, but I'd love to see the older stuff on there too.
