It's funny. The brothers Cooke chiming in here got me thinking.
There's a lot of early 1980s (and late 1970s) AJPW that I hadn't seen before. I was, however, demonstrably more excited when Our Friend in Japan would post something which we, as a community, hadn't yet seen, despite the fact that a huge chunk of what he was posting, new to us or not, was new to me.
On the other hand, I don't really have that feeling for what dataintcash posts. It's cool to have someone like Kris see something he'd never seen before, but in general I'm excited for everything he posts that's new to me and not otherwise online. Some of that is because my wrestling budget for the year is pretty small in general and while I've purchased a bit of lucha over the last few years (80s set, Cota vs Casas hair match before it ended up online, Fredo's GdI comp), I'm probably not going to randomly buy this footage. Some of it is just that I care more about lucha than All Japan.
I think what it really is, however, is that I feel like this stuff hasn't been examined by the community nearly as much, especially through the non-Meltzerian lens of lucha watching. So that these matches become easily accessible to the people watching now is almost as important as us getting our hands on brand new things. I didn't get that sense for the AJPW stuff that had already been out there nearly as much.
